Description:FIELD OF THE INVENTION

[0001] The present invention relates to a self-contained plant care system that autonomously monitors and maintains optimal plant health by integrating environmental sensing, precise irrigation, nutrient delivery, and soil filtration.

BACKGROUND OF THE INVENTION

[0002] Proper plant care is essential for healthy growth, high yield, and disease resistance. Irrigation plays a vital role by providing plants with the necessary water for nutrient absorption, photosynthesis, and overall development. Inadequate or excessive watering can stress plants, leading to poor growth or root diseases. Soil quality inspection is crucial to understand nutrient content, pH levels, and moisture retention capacity, which directly influence plant health. Without regular soil checks, deficiencies or toxicities may go unnoticed. Lack of proper fertilizer reduces the availability of essential nutrients like nitrogen, phosphorus, and potassium, leading to stunted growth, poor flowering, and low fruit or crop yield. Thus, balanced irrigation, soil monitoring, and correct fertilization are key to sustaining plant vitality and maximizing agricultural productivity.

[0003] Traditionally, plant care and irrigation have relied heavily on manual labor or static mechanisms such as drip irrigation, sprinkler systems, and programmable watering timers. While these methods automate certain watering tasks, they generally fail to consider real-time variations in plant health, soil conditions, and environmental factors. Furthermore, such methods often require human supervision for tasks like fertilizer application, pest control, filter placement, or shelter deployment. Additionally, they lack integration of intelligent feedback mechanisms and adaptive responses based on the individual needs of plants, which limits their ability to ensure sustained plant vitality in changing environmental conditions or remote agricultural settings. Therefore, there exists a need in the art to develop a system that is capable of autonomously navigating, analyzing, and responding to specific plant care needs.

[0004] WO2024054182A1 discloses about an agro artificial intelligence fertilization and irrigation automation system which is developed for use in agricultural areas and all areas where agricultural practices are carried out, doesn't need manpower, with the support of artificial intelligence, has modular fertilizer tanks, fertilizer and acid dosing pumps, blower mixer wireless transmitter, soil analysis sensors that automatically determine what the plant needs in water, fertilizer and fertilizer content for each plant and wirelessly notify the central processor, comprises the connection and equipment of the system integrated with the central processor, which decides without the need for operator assistance by interpreting the data coming from the sensors with artificial intelligence.

[0005] US20180271029A1 discloses about a smart grow device includes a set of sensors with at least one camera; a set of care resources; and a controller able to at least partly control the set of care resources based on evaluation of data received from the set of sensors. An automated method of providing plant care includes: retrieving a set of sensor measurements; retrieving model plant data including a set of evaluation criteria; comparing the set of sensor measurements to the set of evaluation criteria in order to determine at least one plant status; and updating active plant data based on the at least one plant status and the set of sensor measurements. An automated plant care system includes: a set of sensors; a set of resources; multiple planters; and at least one controller able to at least partly control the set of resources based on evaluation of data received from the set of sensors.

[0006] Conventionally, many systems have been developed that are capable of providing basic plant watering and nutrient delivery functions. However, these existing systems are incapable of dynamically adapting to the specific and changing needs of individual plants based on real-time environmental and soil data. Additionally, these existing systems also lack comprehensive integration of multiple sensing modalities, such as soil nutrient levels, moisture, temperature, and light intensity, as well as automated mechanisms for precise excavation, filter placement, and tailored nutrient blending.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a system that requires to be capable of autonomously monitoring plant health by collecting and analyzing real-time environmental and soil data to deliver customized care, including precise watering and nutrient administration. In addition, the developed system also needs to provide adaptive excavation and filter placement mechanisms, integrate AI-based plant recognition for targeted care, and enable remote communication for real-time user feedback and control.

[0021] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0022] The present invention relates to a self-contained plant care system that is capable of autonomously managing plant health by analyzing environmental and soil conditions, delivering precise irrigation and nutrient blends, and performing adaptive soil filtration. Additionally, the system is also capable of remotely communicating real-time data to users, deploying protective covers to shield plants from adverse weather, and adjusting care routines dynamically to optimize plant growth with minimal human intervention.

[0023] Referring to Figure 1 and 2, an isometric view of a self-contained plant care system and an isometric view of a concrete filter module associated with the proposed system are illustrated, respectively, comprising a mobile body 101 equipped with multiple motorized wheels 102 connected via a piston bar 103, a storage unit 104 arranged with the body 101 for storing multiple concrete filter module 105, the filter module 105 comprises of multiple motorized iris apertures 201 and a protective cover assembly 202 comprising a hydraulic piston-actuated sheet roller 203 and expandable drawer-connected plates 204, a digging assembly 106 arranged with the body 101, the digging assembly 106 comprises a hydraulic piston 107, an expandable circular frame 108 with pulley arrangement 109.

[0024] Figure 1 and 2 further illustrates a soil cutting blade 110 mounted on the frame 108, a holding unit 111 is installed on the body 101 and comprises of an expandable bar 112 connected to a clamping unit 113, an artificial intelligence-based imaging unit 114 mounted on the body 101, a mixing chamber 115 and a fertilizer chamber 116 arranged within the body 101, a multi-sectioned container 117 mounted in the body 101, a display panel 118, a speaker 119 and a microphone 120 are installed on the body 101.

[0025] The system disclosed herein comprises of a mobile body 101 that serves as the primary structural framework for housing various components and functional modules associated with the system and facilitates movement across diverse terrains. The body 101 is equipped with multiple motorized wheels 102 for providing structural integrity and smooth, multidirectional movement across varying terrains such as gardens, greenhouses, or outdoor agricultural plots. Each of the wheels 102 are mechanically linked via a piston bar 103 for providing positional control. The piston bar 103 dynamically adjusts the relative positioning of the wheels 102 to enable height adjustment and stability correction on uneven surfaces. to precisely navigate towards individual plants or designated coordinates within the operating field

[0026] A user is required to activate the system manually by pressing a button installed on the body 101 and linked with an inbuilt microcontroller associated with the system. The button is a type of switch that is internally connected with the system via multiple circuits that upon pressing by the user, the circuits get closed and starts conduction of electricity that tends to activate the system and vice versa.

[0027] Upon activation of the system, the user is required to access a microphone 120 installed on the body 101 to provide audio input regarding the specific plant that is to be cared. any custom instructions relevant to the user’s horticultural goals. The microphone 120 receives the user voice commands and converts the sound energy emitted by the user into electrical energy. Inside the microphone 120, a diaphragm made of plastic is present that moves back and forth when the sound wave hits the diaphragm, which then moves a coil attached to the diaphragm in the same way in order to generate an electrical signal proportional to the sound. The electric signal from coil flows to an amplifier which amplifies the electrical signal. The amplified electrical signal is then sent to an inbuilt microcontroller linked to the microphone 120.

[0028] Upon receiving and processing the signal from the microphone 120, the microcontroller recognizes the user input voice command and accordingly activates an artificial intelligence-based imaging unit 114 mounted on the body 101 to identify the target plant location. The artificial intelligence-based imaging unit 114 comprises of a high-resolution camera lens, digital camera sensor and a processor, wherein the lens captures multiple images from different angles and perspectives in vicinity of the body 101 with the help of digital camera sensor for providing comprehensive coverage of the surrounding.

[0029] The captured images then go through pre-processing steps by the processor integrated with the imaging unit 114. The artificial intelligence protocols integrated into the processor, including machine learning and computer vision protocols, optimize image processing by enhancing feature extraction and classification. The captured images undergo pre-processing steps such as adjusting brightness, contrast, and noise removal to enhance quality. These refined images are transmitted to the microcontroller linked with the processor in the form of electrical signals.

[0030] The microcontroller processes the received signals in order to evaluate a 3D (three-dimensional) map of the surroundings, the evaluated map is further sent in the form of digital signals, to a display panel 118 provided on the body 101 for displaying the evaluated map. The display panel 118 processes incoming signals from the microcontroller and convert digital data into visual output, for allowing the user to view the evaluated map and select a portion of the ground surface over which the user desires to carve hollow slots for plant care.

[0031] The display panel 118 used herein is a type of Liquid Crystal Display (LCD) that detect touch input from the user. It consists of both an input unit (preferably a capacitive touch panel) and an output unit (a visual display). The capacitive touch panel is layered on the top of the visual display. The touch panel consists of an insulator such as glass, coated with a transparent conductor, such as indium tin oxide (ITO). When the user touches the surface of the display panel 118 to select a location, the electrostatic field of the display panel 118 gets distorted, that is measured as a change in capacitance. This change in capacitance is used to determine the location of the touch. The determined location of the touch is then sent in the form of electrical signals to the microcontroller linked with the display panel 118.

[0032] The microcontroller further processes the user input commands to determine the portion of the ground surface over which the user desires to carve hollow slots. Based on the determine portion, the microcontroller actuates the motorized wheels 102 to maneuver and position the body 101 in proximity to the user-selected portion of the ground surface.

[0033] The motorized wheels 102 are a circular object that revolves on an axle to enable the body to translate easily. A hub motor is integrated into the hub of the wheels 102. The hub motor is an electric motor that comprises of a series of permanent magnets and electromagnetic coils. When the motor is activated, a magnetic field is set up in the coil and when the magnetic field of the coil interacts with the magnetic field of the permanent magnets, a magnetic torque is generated causing the stator of the motor to turn and that provides the rotational motion to the wheels 102 to ensure smooth movement of the body 101 over the ground surface in a manner to position the body 101 near the user-specified portion of the ground surface.

[0034] Simultaneously, the microcontroller actuates the piston bar 103 to extend/retract in order to adjust the lateral position of the mobile body 101, for enabling precise alignment with the target plant to ensure that the components are aligned properly with respect to the surface. The extension of the piston bar 103 is powered by a pneumatic unit associated with the system that includes an air compressor, air cylinder, air valves and piston which works in collaboration to aid in extension and retraction of the bar 103.

[0035] The air compressor used herein extract the air from surrounding and increases the pressure of the air by reducing the volume of the air. The air compressor is consisting of two main parts including a motor and a pump. The motor powers the compressor pump which uses the energy from the motor drive to draw in atmospheric air and compress to elevated pressure. The compressed air is then sent through a discharge tube into the cylinder across the valve. The compressed air in the cylinder tends to pushes out the piston to extend. The piston is attached to the bar 103, wherein the extension/ retraction of the piston corresponds to the extension/ retraction of the bar 103 to adjust the lateral position of the body 101.

[0036] A storage unit 104 is arranged over the body 101 and stored with multiple concrete filter module 105 of varying dimensions, wherein upon positioning of the body 101, the microcontroller actuates a digging assembly 106 arranged with the body 101 for excavating soil matching the dimensions of concrete filter module 105 to be installed, as specified by the user via the microphone 120. The digging assembly 106 includes a hydraulic piston 107 with adjustable extension, an expandable circular frame 108 with pulley arrangement 109, and a soil cutting blade 110 mounted on the frame 108.

[0037] Upon actuation of the digging assembly 106, the pulley arrangement 109 performs smooth expansion and contraction of the circular frame 108, for allowing the cutting blade 110 to adjust its diameter accurately according to the required excavation size. The pulley arrangement 109 used herein comprises a series of interconnected pulleys, each connected to a small motor controlled by the microcontroller. Based on the dimensions of filter module 105 to be installed, the microcontroller activates the motors to either expand or contract the pulleys in order to increase or decrease the diameter of the circular frame 108 for allowing the cutting blade 110 to encircle the digging area.

[0038] Once the frame 108 size is adjusted, the microcontroller actuates the hydraulic piston 107 to extend the frame 108 vertically downward for allowing the blade 110 to penetrate the ground to the desired depth specified by the user for excavating soil matching the dimensions of filter module 105. The hydraulic piston 107 includes an oil pump, oil cylinders, and oil valves which works in collaboration to apply optimal amount of force over the blade 110.

[0039] The hydraulic piston 107 operates by converting hydraulic pressure into mechanical motion. The piston 107 consists of a cylinder, connected to a piston rod. On actuation, hydraulic fluid is pumped into one side of the cylinder, it pushes the piston 107, causing the piston rod to extend and generate linear motion. Conversely, when fluid is pumped into the other side of the cylinder, it retracts the piston rod. By controlling the flow and pressure of hydraulic fluid, the hydraulic piston 107 applies optimal amount of force over the blade 110 for creating an accurately sized excavation hole that perfectly matches the dimensions of the concrete filter module 105.

[0040] A holding unit 111 comprising an expandable bar 112 connected to a clamping unit 113, is installed on the body 101, wherein upon excavation of the hole, the microcontroller actuates the expandable bar 112 in synchronization with the clamping unit 113 to extend towards the storage unit 104 for allowing the clamping unit 113 to securely grip the filter module 105 from the storage unit 104. The extension/retraction of the expandable bar 112 is powered by a pneumatic unit associated with the system in the same manner as described above.

[0041] The clamping unit 113 consists of a motorized C-shaped claw, a small electric motor, a gear or threaded rod arrangement, and a soft lining material inside the claw. The microcontroller sends signals to the motor to actuate the clamping unit 113. When a signal is received, the motor turns, driving the gear or threaded rod arrangement. This arrangement converts the rotational motion of the motor into linear movement, allowing the C-shaped claw to converge and acquire a grip over the filter module 105.

[0042] Once the filter module 105 is gripped, the microcontroller commands the bar 112 to further extend/retract and position the filter module 105 over the excavated hole with precise alignment, as guided by the imaging unit 114 and an angle sensor embedded with the holding unit 111. The angle sensor comprises a MEMS (Micro-Electro-Mechanical Systems)-based inclinometer or gyroscopic sensor, and signal processing unit. When the filter module 105 is held by the clamping unit 113, the angle sensor continuously detects its tilt or orientation along specific axes. These measurements are compared to a predefined vertical or angular reference aligned with the excavated hole. If any misalignment is detected, corrective feedback is sent to the expandable bar 112 to adjust the module’s orientation.

[0043] Once the filter module 105 is properly aligned, the microcontroller directs the clamp to release the filter module 105, for allowing the filter module 105 to be placed accurately within the excavated hole. Each filter module 105 integrated into the system is equipped with a dedicated RFID (Radio Frequency Identification) tag that serves the dual purpose of identification and real-time data tracking. These RFID tags store specific metadata such as the filter’s unique ID, size dimensions, installation date, nutrient release settings, and prior usage statistics.

[0044] A RFID reader mounted on the body 101 actively scans these tags during the installation process to ensure the correct filter module 105 is selected and deployed for a given plant based on its needs. The RFID reader scans RFID tags by emitting radio waves and receiving the signals reflected back by the tags. The RFID reader includes a transmitter, receiver, antenna, and a signal processor. When the RFID reader is powered, its transmitter generates a radio frequency signal through the antenna. This signal energizes nearby passive RFID tags, which then transmit their stored data (such as a unique ID) back to the reader using modulated radio waves. The receiver in the reader captures these signals, which are processed and decoded by the signal processor. The decoded tag data is then sent to the microcontroller that processes the data to ensure the correct filter module 105 is selected and deployed for a given plant based on its needs.

[0045] Upon placement of the filter module 105, the microcontroller activates a sensor array arranged within the filter module 105 to initiate real-time monitoring of environmental and soil parameters surrounding the plant. The sensor array includes at least one soil moisture sensor, NPK nutrient sensor, temperature sensor, humidity sensor, and a light intensity sensor. These sensors operate simultaneously to capture comprehensive data on both internal soil health and external climatic parameters.

[0046] The soil moisture sensor used herein is a non-contact moisture sensor which operate based on capacitance principle. An electromagnetic field is generated by an oscillator circuit within the sensor. This field extends to the soil. When the soil is dry, its dielectric constant is relatively low. However, when moisture is present, the dielectric constant increases. This change in dielectric constant alters the capacitance between the sensor and the surface. The sensor measures the changes in capacitance caused by the presence of moisture. This change is converted into an electrical signal, which is then transferred to the linked microcontroller for interpretation.

[0047] The NPK sensor detect the content of nitrogen, phosphorus and potassium in the soil, and judges the fertility of the soil by detecting the electrical conductivity transformation caused by different nitrogen, phosphorus and potassium concentrations in the soil. Therefore, the received signals are sent to the microcontroller for further processing and the microcontroller compares the conductivity value with the pre-fed range to determine nutrient levels or the NPK value of the soil.

[0048] The temperature sensor used herein detect the temperature by optical analysis of the infrared radiation present around the soil. On activation, the sensor employs a lens to focus the infrared radiation emitting from the soil, onto a detector known as a thermopile. When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat. Voltage output is produced in proportion to the incident infrared energy. The detector uses this output to detect the temperature of the soil. The measured temperature is then converted into electrical signal which is received by the microcontroller.

[0049] The humidity sensor measures atmospheric moisture by detecting changes in electrical properties due to humidity levels. The humidity sensor comprises of a sensing element (capacitive or resistive), substrate, electrodes, and signal conditioning circuit. In a capacitive humidity sensor, the sensing element includes a hygroscopic dielectric material placed between two electrodes. As atmospheric moisture changes, the dielectric constant of the material shifts, altering the capacitance. In resistive sensor, moisture changes the conductivity of a hygroscopic film, varying resistance. These changes are converted into electrical signals by the signal conditioning circuit and sent to the microcontroller.

[0050] The light intensity sensor measures ambient illumination by detecting the intensity of incident light and converting it into an electrical signal. The light intensity sensor includes a photodiode or phototransistor, signal conditioning circuit, and an analog-to-digital converter (ADC). When light strikes the photodiode or phototransistor, it generates a current proportional to the light intensity. This analog current is passed through the signal conditioning circuit, which amplifies and filters the signal. The processed signal is then sent to the ADC, which digitizes it and transmit to the microcontroller.

[0051] The microcontroller processes the collected/received data from all the sensors of the sensing array to evaluate the immediate and long-term requirements of the plant for optimal growth and health. Based on parameters such as current soil moisture, nutrient content, ambient temperature, humidity, and light intensity, the microcontroller performs real-time analysis to determine the precise quantity of water and nutrients to be dispensed. The microcontroller cross-references these sensor readings with pre-fed plant-specific growth profiles and environmental thresholds stored in the memory.

[0052] A fertilizer chamber 116 is arranged within the body 101 and divided into multiple compartments, each configured to store a different type of fertilizer and water. Each compartment is arranged with an iris lid having a conduit that opens into a mixing chamber 115 arranged below the fertilizer chamber 116. Based on the plant’s conditions as detected by the imaging unit 114 and the sensor array, the microcontroller evaluates the specific nutrient needs of the plant and selectively actuates the iris lids of the required compartments, for allowing the appropriate type and quantity of fertilizers and water to flow into the mixing chamber 115.

[0053] The iris lid mentioned herein, consists of a ring in bottom configured with multiple slots along periphery, multiple number of blades and blade actuating ring on the top. The blades are pivotally jointed with blade actuating ring and the base plate are hooked over the blade. The blade actuating ring is rotated clock and anti-clock wise by a DC motor embedded in ball actuating ring which results in opening and closing of the lid to release the appropriate type and quantity of fertilizers and water into the mixing chamber 115.

[0054] Upon dispensing of the nutrients and water from the fertilizer chamber 116, the microcontroller actuates multiple vibrating units installed within the mixing chamber 115 to thoroughly agitate and homogenize the contents. The vibration ensures that the varying fertilizer components and water mix uniformly, eliminating the possibility of sedimentation or uneven distribution of nutrients.

[0055] The vibrating units work by converting electrical energy into mechanical vibrations. The units consist of a small motor with unbalanced weight attached to its shaft. On actuation by the microcontroller, the motor spins the unbalanced weight creates a vibrating motion, which shakes the mixing chamber 115 to generate vibrational sensations of pre-defined intensity, that is imparted to the fertilizer components and water to prepare a uniform mixture.

[0056] Once the desired consistency and homogeneity are achieved, the microcontroller actuates an electronic valve arranged at the bottom of the mixing chamber 115 to open and dispense the prepared mixture through a conduit directly into either the concrete filter module 105 or the soil around the plant. The electronic valve consists of a gate, nozzle and a magnetic coil which is energized by the microcontroller, on energizing of the magnetic coil, a magnetic force is generated which pushes the gate to open for dispensing a pre-set amount of prepared mixture into the filter module 105 or the soil around the plant. After the required amount of mixture is dispensed, the microcontroller sends a command to de-energize the magnetic coil in order to close the valve.

[0057] Based on the real-time data from the sensor array, if deficiencies or imbalances are detected, the microcontroller actuates multiple motorized iris apertures 201 installed over the filter module 105 to open and release appropriate amounts of water and nutrient solution in controlled amounts for irrigating and meeting nutrient requirements for the plant. The motorized iris apertures 201 used herein works in the same manner as described above for the iris lids.

[0058] A multi-sectioned container 117 is integrated into the body 101. Each section of the container 117 accommodates a distinct filtration material such as activated charcoal, crushed stone, coconut coir, biochar, and clay balls. These materials are selected for their complementary properties in purifying water and enhancing soil aeration and nutrient retention. Each section is operatively connected to a vibration-assisted conduit pump, wherein upon receiving a signal from the microcontroller, the conduit pump is actuated to vibrate and transport the specific material from its respective section into the concrete filter.

[0059] The materials are dispensed in a predetermined order, for forming distinct filtration layers that collectively support water purification, root aeration, microbial growth, and moisture retention. The microcontroller coordinates the sequential activation of each conduit pump based on either predefined filter construction protocols or real-time data from the sensor array. This enables automated, adaptive preparation of filtration beds suitable for varying soil and plant requirements, thereby enhancing the overall effectiveness of water and nutrient delivery to the plant's root zone.

[0060] Further, if external conditions such as excessive heat or light are detected by the sensor array, the microcontroller actuates a protective cover assembly 202 to shield the plant from environmental stress. The protective cover assembly 202 comprises of a hydraulic piston-actuated sheet roller 203 wrapped with a weather-resistant flexible sheet and expandable drawer-connected plates 204. Upon actuation, the hydraulic piston extends to unroll the flexible sheet from the roller 203 and gradually drapes it over the plant area. Simultaneously, the drawer-connected plates 204 expand laterally to secure and support the edges of the sheet, ensuring complete and stable coverage against sunlight, heat, or other harsh conditions.

[0061] Each drawer-connected plate is mounted on telescopic guiding rails and connected to linear actuators or servo motors that are controlled by the microcontroller. Upon activation, the microcontroller sends signals to the actuators, prompting the plates 204 to slide outward in a coordinated manner. As the plates 204 extend, they simultaneously pull and stretch the attached flexible sheet to form a protective canopy over the plant, for shielding the plant from environmental stress.

[0062] The system is configured to analyze plant-specific requirements by continuously monitoring environmental and soil parameters through the integrated sensor array and imaging unit 114. These components work together to gather real-time data regarding soil moisture levels, nutrient content, ambient temperature, humidity, and light intensity, as well as visual cues from the plant such as foliage density, color, and posture. This comprehensive dataset is processed by the microcontroller, which applies predefined logic and adaptive protocols to determine the precise care routine required for each plant.

[0063] Based on the analyzed conditions, the microcontroller dynamically adjusts operational routines, such as water and fertilizer dispensing, deployment of protective coverings, and timing of care interventions to match the real-time needs of the plant. Furthermore, the system is equipped with a Wi-Fi-enabled IoT interface that facilitates seamless remote communication. User is able to monitor plant status, receive alerts, and modify operational parameters through a computing unit wirelessly linked with the microcontroller. The user interface displays real-time feedback from the sensors and imaging unit 114, allowing the user to intervene manually if desired.

[0064] A weight sensor installed in the storage unit 104, continuously monitor the weight of the accommodate filter module 105. The weight sensor used herein is a particular kind of transducer, more especially a weight transducer, which transform a mechanical force that is applied as an input, by the weight of the filter module 105, into a change in electrical resistance, which varies proportionally to the force being applied to the sensor. This change in electrical resistance is detected by the microcontroller linked with the sensor, in the form of an electrical signal.

[0065] The microcontroller processes the received signals from the weight sensors in order to measure the weight of the filter module 105, and compares the detected weight with a threshold value of weight that is pre-feed in the database of the microcontroller. In case the detected value recedes the threshold, the microcontroller activates a speaker 119 installed on the body 101 to notify the user to refill the storage unit 104. The speaker 119 consists of audio information, which is in the form of recorded voice, synthesized voice, or other sounds, generated or stored as digital data.

[0066] The digital audio data is converted into analog electrical signals. Further the analog signal is amplified by an amplifier and the amplified electrical audio signal is then sent to a diaphragm, which is typically made of a lightweight and rigid material like paper, plastic, or metal, and is designed to vibrate or move back and forth when electrical signals are fed to it. This movement creates pressure variations in the surrounding air, generating sound waves in order to generate the audible sound for notifying the user to refill the storage unit 104.

[0067] Lastly, a battery is associated with the system which is connected to the microcontroller that supplies current to all the electrically powered components that needs an amount of electric power to perform their functions and operation in an efficient manner. The battery utilized here, is generally a dry battery which is made up of Lithium-ion material that gives the system a long-lasting as well as an efficient DC (Direct Current) current which helps every component to function properly in an efficient manner. As the system is battery operated and do not need any electrical voltage for functioning.
