Description:POWER-SAVING SYSTEM USING HUMAN PRESENCE DETECTION AND METHOD THEREOF
BACKGROUND
Technical Field
[0001] The embodiment herein generally relates to a power saving systems and more particularly, to a power-saving system using human presence detection and method thereof.
Description of the Related Art
[0002] Existing power-saving systems often rely on motion sensors, timers, or manual control, which are prone to inaccuracies. Motion sensors may fail to detect stationary occupants or trigger falsely due to minor movements. Timers operate on fixed schedules, ignoring real-time occupancy. These systems result in energy wastage or user inconvenience due to premature shutoff or unnecessary operation of appliances.
[0003] There is a need for a more accurate and automated solution that can detect actual occupancy in real time to enable reliable automatic control of electrical appliances for reducing energy consumption, lowering costs, and improving user comfort without requiring manual intervention.
[0004] Accordingly, there remains a need for a power-saving system using human presence detection and method thereof.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[00019] The embodiments herein and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments that are illustrated in the accompanying drawings and detailed in the following description. Descriptions of well-known components and processing techniques are omitted so as to not unnecessarily obscure the embodiments herein. The examples used herein are intended merely to facilitate an understanding of ways in which the embodiments herein may be practiced and to further enable those of skill in the art to practice the embodiments herein. Accordingly, the examples should not be construed as limiting the scope of the embodiments herein.
[00020] As mentioned, there remains a need for a power-saving system using human presence detection and method thereof. Referring now to the drawings, and more particularly to FIGs. 1 through 2, where similar reference characters denote corresponding features consistently throughout the figures, there are shown preferred embodiments.
[00021] FIG. 1 illustrates a power-saving system 100 using human presence detection, according to some embodiments herein. The system 100 includes at least two Infrared (IR) sensors 102A-102B, a microcontroller 104, counter logic 106, a relay module 108, electrical appliances 110, and an alert module 112. The at least two Infrared (IR) sensors 102A-102B are configured side by side of a doorway. The at least two IR sensors 102A-102B detect a direction of movement near the doorway.
[00022] Further, the microcontroller 104 is configured to process signals received from the at least two IR sensors 102A-102B. The microcontroller 104 based on the processed signal is further configured to check if the first IR sensor 102A is triggered then the microcontroller 104 102A-102B registers that someone has entered the room and the counter logic 106 counts count +1. If the second IR sensor 102B is triggered then the microcontroller 104 registers that someone has existed the room and the counter logic 106 counts count −1.
[00023] Furthermore, the relay module 108 is configured as a smart switch to control a power supply to the room’s electrical appliances 110. The smart switch is used to ON/OFF the electrical appliances 110. Further a manual switch can also be used to ON/OFF the electrical appliances 110 in case of emergency. The alert module 112 is activated when the counter logic 106 is zero, wherein the activated alert module 112 indicates that the room is now empty. In a non-limiting example, the electrical appliances may include lights, fans, air conditioners, and the like. The microcontroller 104 is Arduino, ESP32, or Raspberry Pi. The alert module 112 is a LED or buzzer. The smartphones may use platforms such Blynk, Home Assistant, or Firebase, to monitor occupancy, receive alerts, and manually control appliances.
[00024] In some embodiments, the system 100 comprises an IoT connectivity module 114. The IoT connectivity module 114 is configured to provide a Wi-Fi connection to the system for remote access to monitor occupancy, receive alerts, and manually control electrical appliance via a smartphone. The counter logic 106 keeps real-time track of a number of people inside the room.
[00025] In some embodiments, the system 100 automatically manage the electrical usage of a room based on human presence. The system uses infrared (IR) sensors placed at the entrance to count the number of people entering and exiting. It increases the count by one when someone enters and decreases it when someone exits. When the count reaches zero, the system recognizes that the room is empty and automatically turns off all connected electrical appliances such as lights, fans, and air conditioners. It may also give an alert indicating the room is vacant. This solution helps in reducing electricity wastage, lowering energy bills, and promoting environmental sustainability. It is simple to install, easy to use, and suitable for homes, offices, classrooms, and other indoor spaces. The device can also be upgraded to include remote monitoring and smart control features.
[00026] In some embodiments, the system 100 can use camera-based counting, PIR motion sensors, ultrasonic sensors, Bluetooth or RFID detection, pressure or floor sensors, and voice-activated control with presence sensing. The camera-based counting use a small camera with image processing (AI or OpenCV) to detect and count people instead of IR sensors. This improves accuracy and works better in large rooms or wide doors. The PIR motion sensors use Passive Infrared (PIR) motion sensors to detect human presence. If no motion is detected for a certain time, the system assumes the room is empty and turns off the power.
[00027] The ultrasonic sensors use ultrasonic sensors to measure the distance and detect movement through a doorway, helping to count people entering or exiting. The Bluetooth or RFID detection detect smartphones, smartwatches, or RFID tags carried by users. If no registered devices are detected, the system assumes the room is empty. The pressure or floor sensors install pressure-sensitive mats or floor sensors to detect foot traffic, useful in environments where optical sensors might not work well. The voice-activated control with presence sensing combine voice assistants (like Alexa or Google Assistant) with a presence sensor. Users can give voice commands, and the system can auto-turn off appliances when no one responds for a set period.
The system (100) uses Smart Plug-Based Appliance Control Instead of cutting power to the entire room, use smart plugs to control specific appliances (like fans, lights, AC units) individually.
[00028] FIG. 2 illustrates a flow chart shows a method 200 for providing a power-saving system using human presence detection, according to some embodiments herein. At step 202, the method 200 includes configuring, at least two Infrared (IR) sensors 102A-102B, side by side of a doorway. The at least two IR sensors 102A-102B detect a direction of movement near the doorway. At step 204, the method 200 includes configuring, a microcontroller 104, to process signals received from the at least two IR sensors. The microcontroller 104 based on the processed signal is further configured to check if the first IR sensor 102A is triggered then the microcontroller 104 registers that someone has entered the room and the counter logic 106 counts count +1. If the second IR sensor 102B is triggered then the microcontroller 104 registers that someone has existed the room and the counter logic 106 counts count −1.
[00029] At step 206, the method 200 includes configuring, a relay module 108, as a smart switch to control a power supply to the room’s electrical appliances 110. At step 208, the method 200 includes activating, an alert module 112, when the counter logic 106 is zero, wherein the activated alert module 112 indicates that the room is now empty.
[00030] An advantage of the system 100 is that the system 100 saves electricity by turning off lights, fans, and other appliances when no one is in the room, so no power is wasted.
[00031] An advantage of the system 100 is that the system 100 saves money by reducing electricity use, it helps lower your electricity bill every month.
[00032] An advantage of the system 100 is that the system 100 works automatically for example, you don’t have to remember to turn things off the device does it for you.
[00033] An advantage of the system 100 is that the system 100 makes places safer has the system turns off devices that might overheat or cause problems if left on too long.
[00034] An advantage of the system 100 is that the system 100 is good for the environment as the system use less power means less pollution and helps protect the planet.
