The present invention generally relates to the field of waste collector. The invention, particularly relates to a smart dustbin which is capable of opening and closing automatically, detecting radioactive materials, sensing the proximity of the person/object, and sensing the moisture content in the waste materials. The smart dustbin comprises various mechanical, electronic, electromechanical components.

BACKGROUND OF THE INVENTION
Today, much waste or waste material from homes, residences, businesses, stores, convenience stores, fast food chains, restaurants, retail locations, offices, schools, and commercial, institutional, and government environments or locations is discarded by individuals (e.g. mainly homeowners, renters, occupants, workers, consumers, employees, students) into waste receptacles (e.g. waste containers such as trash containers, trash receptacles, trash cans, garbage containers, garbage receptacles, and garbage cans) provided onsite. These waste receptacles typically are fitted with disposable plastic bags, which can be closed when filled, removed from the waste receptacles, and then disposed of in waste containers (e.g. trash cans, garbage cans, and dumpsters) usually located outside the buildings and/or adjacent to the parking lots of these locations to facilitate removal by a waste disposal service.
Typically, the waste is not sorted onsite, and all different types of waste are discarded into the same waste receptacles resulting in a wide variety of waste mixed together, including trash, garbage, paper products plastic products, food waste, and other waste items defining a general waste stream. The plastic bags filled with waste are thrown into a garbage can or dumpster, and mixed with other loose waste or plastic bags containing waste. This waste is transported in dumpsters or garbage trucks to landfills, and typically not sorted before land filling.
Due to the large amount of labor involved with sorting, it is desirable that consumers (e.g. individuals, end users, customers, students, employees, workers, contractors) of food and beverage products immediately begin the process of sorting the waste food and beverage products by placing these items in marked waste collection containers (e.g. receptacles, bins, vessels). For example, consumers immediately place used paper cups or plastic bottles into separately marked waste collection containers to begin the process of effectively sorting particular types of waste. The marked waste collection containers, preferably contain a removable disposable bag(s) or liner(s), which when filled can be removed and then disposed of into waste containers such as garbage cans and dumpsters. It becomes very difficult to put waste materials inside the garbage or dust bin without touching the waste collector/dust bin.

Human activities create waste, and it is the way these wastes are handled, stored, collected and disposed of, which can pose risks to the environment and to public health. In urban areas, especially in the rapid urbanizing cities of the developing world, problems and issues of Solid Waste Management (SWM) are of immediate importance. This has been acknowledged by most governments, however rapid population growth overwhelms the capacity of most municipal authorities to provide even the most basic services. Typically one to two thirds of the solid waste generated is not collected. As a result, the uncollected waste, which is often also mixed with human and animal excreta, is dumped indiscriminately in the streets and in drains, so contributing to flooding, breeding of insect and rodent vectors and the spread of diseases. Furthermore, even collected waste is often disposed of in uncontrolled dumpsites and/or burnt, polluting water resources and air. Throughout the developing world it is the urban poor, often in the peri-urban areas, that suffer most from the life-threatening conditions deriving from deficient SWM, as municipal authorities tend to allocate their limited financial resources to the richer areas of higher tax yields where citizens with more political pressure reside. Usually as income of the residents increases, part of the wealth is used to avoid exposure to the environmental problems close to home, but as waste generation also increases with increasing wealth, the problems are simply shifted elsewhere. Thus even as environmental problems at the household or neighborhood level may recede in higher income areas, citywide and regional environmental degradation due to a deficient SWM remains or increases.
When it comes to maintaining health, safety, and cleanliness in the home or workplace, choosing the best trash or garbage can is actually important. Supplying employees and customers with easily accessible trash cans will enable them to consistently place trash or material for recycling in the right container. Overflowing trash cans always look sloppy and make the overall environment of the workplace or household unhealthy, unfavorable and unsafe. That’s why businesses and households alike not only need the right size of trash and garbage cans but also a sufficient number of such containers that are strategically positioned to minimize the travel time of people using them. For easy handling, larger trash bins benefit from handles, dollies, wheels or rollers. Tops of trash cans are also important. Options include tops that stay up, removable tops, and vented options. Rectangular shapes can provide better storage efficiency for multiple trash bins than circular design.
Fig. 1 depicts an exemplary a smart dustbin according to one of the preferred embodiment of the present invention. Fig. 2 depicts a second exemplary a smart dustbin according to one of the preferred embodiment of the present invention. The present invention which is capable of opening and closing automatically, detecting radioactive materials, sensing the proximity of the person/object, and sensing the moisture content in the waste materials. The smart dustbin comprises various mechanical, electronic, electromechanical components. The smart dustbin of the present invention can be operated automatically. Two different embodiments of the present invention are presented in the Figs. 1 and 2. Fig. 1 represents the smart dustbin is kind of single compartment container while the Fig. 2 depicts the smart dustbin having two separate compartments. The smart dustbin (100 / 200) comprises: a. a container wall (101 / 201); b. a container cover (102 / 202); c. a radioisotope identification device (RIID) (103 / 203); d. a plurality of ultrasonic sensors (104 / 204); e. an Arduino Uno (105 / 205); f. an Infrared sensor (106 / 206)); g. a buzzer (107 / 207); h. a servo motor (108 / 208); i. a moisture sensor (109 / 209). The said plurality of ultrasonic sensors (104 / 204) is placed to sense the proximity of the movement of the person or the object. The ultrasonic sensors assists the smart dustbin to find out whether any person or any object is coming closer or not. Based on that it send signals to the Arduino Uno (105 / 205) microcontroller.
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. The board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. The board has 14 digital I/O pins (six capable of PWM output), 6 analog I/O pins, and is programmable with the Arduino IDE (Integrated Development Environment), via a type B USB cable. It can be powered by the USB cable or by an external 9-volt battery, though it accepts voltages between 7 and 20 volts. The ultrasonic sensors of the present invention ultrasonic sensor is an instrument that measures the distance to an object using ultrasonic sound waves. An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity. The container lid or cover (102/202) comprises a moisture sensor (109/209) which is configured to find whether the waste is dry or wet and accordingly sending signals to the microcontroller. The smart dustbin of the present invention also comprises an infrared sensor (IR sensor) (206/106). The infrared sensor (IR sensor) is a radiation-sensitive optoelectronic component with a spectral sensitivity in the infrared wavelength range 780 nm … 50 µm. The buzzer (107 / 207) can be either electromechanical or piezoelectric or mechanical type. An audio signaling device like a beeper or buzzer may be electromechanical or piezoelectric or mechanical type. The main function of this is to convert the signal from audio to sound. Generally, it is powered through DC voltage and used in timers, alarm devices, printers, alarms, computers, etc. Based on the various designs, it can generate different sounds like alarm, music, bell & siren.
The smart dustbin of the present invention comprises a radioisotope identification device (RIID) (103 / 203). The radioisotope identification device (RIID) (103 / 203) which are designed to determine the identity of radioactive materials by measuring the energy of the emitted gamma rays. Law enforcement, customs, and other personnel are being equipped with RIIDs as part of a national strategy to interdict illicit movement of radioactive material. When radiation sources are detected by screening devices such as radiation portal monitors or radiation pagers, RIIDs are used to determine whether the source of radioactivity constitutes a high-level threat. Radiological emergency personnel, firefighters and other response personnel also use RIIDs for situational assessment during radiological emergencies.
The servo motor (108 / 208) is coupled with said arduino uno (105/205) and said plurality of ultrasonic sensors (104/204) and assisting opening and closing of said container cover (102/202). The servo motor is a rotary actuator that allows for precise control of angular position. It consists of a motor coupled to a sensor for position feedback. It also requires a servo drive to complete the system. The drive uses the feedback sensor to precisely control the rotary position of the motor.
The smart dustbin is capable of detecting persons/objects in the nearby vicinity and communicating signals to the microcontroller for taking further action. The Arduino Uno (105 / 205) also configured to find out the quantity filled in the smart dustbin. In case, the dustbin is filled completely then sending out the buzzer signals to notify the person that the dustbin is full.

The use or working of the Smart dustbin is explained below:
STEP 1: The first stage of our IoT based smart dustbin has a lid connected with a servo motor which operates when a person comes in contact with the Ultrasonic Sensor in an approximate range of 20 – 25cm. Taking it further the lid remains for around 3 sec in order to let the person to put the garbage in it. Once the person is done with it the lid closes.
STEP 2: Now about the further working of the dustbin after the first stage the second stage gets activated that is the segregation process. Once the person is done with it the second lid gets in action of determining whether the garbage is wet or dry it happens in a way that the garbage present on the second lid has a moisture sensor in it whereas it also has a IR Sensor in it which sense the presence of garbage present upon the lid then the moisture sensor determines whether the garbage present in it is wet or dry. Once the moisture sensor is done with it the servo motor gets the command of rotating and putting the garbage in the respected side.
STEP 3: Once all these steps are done then we move towards the final step that is fulfill of the dustbin once the dustbin gets filled up to a certain level or a mark then the depth sensor present in it gets activated and send a signal using the GSM Module to the registered number with a typed message that “YOUR DUSTBIN IS FULL”. With this message a beep of 3 sec is followed until the authority don’t get it vacant. Once it is vacant the its again ready for use.
STEP 4: RRID - Radioisotope Identification Devices (RIIDs) are components that are designed to determine the identity of radioactive materials by measuring the energy of the emitted gamma rays. Law enforcement, customs, and other personnel are being equipped with RIIDs as part of a national strategy to interdict illicit movement of radioactive material. When radiation sources are detected by screening devices such as radiation portal monitors or radiation pagers, RIIDs are used to determine whether the source of radioactivity constitutes a high-level threat. Radiological emergency personnel, firefighters and other response personnel also use RIIDs for situational assessment during radiological emergencies. The RRID sensors are connected inside the dustbin for measuring the energy of the gamma rays to identify the radioactive materials present inside it or upto certain range. And once it senses gamma energy an alarm would be raised as well as a message would be sent to the monitoring system regarding the material with the location of the dustbin or with the number of the dustbin which would be easy to locate.
