INTELLIGENT OBJECT COUNTING SYSTEM
The main aim of the project is to count the number of persons present in a room and display it in on seven segment displays. Use of embedded technology makes this closed loop feedback control system efficient and reliable. Microcontroller (AT89S52) allows dynamic and faster control. Liquid crystal display (LCD) makes the system user-friendly. AT89S52 micro controller is the heart of the circuit as it controls all the functions.
The system comprises of two IR Transmitter-Receiver pairs, one of which is located in front of the door outside the room. The other pair is located inside the room. Whenever a person tries to enter into the room, the receiver of first IR pair identifies the person. Then the microcontroller identifies this and increments the count to 1. Similarly as the person enters into the room, the count will be incremented and this count will be displayed on LCD.
This project is also applicable to count the objects in a predefined area. The main application of this project can be seen in manufacturing and production industries like bottle filling, pharmaceutical industries etc. The IR transmitter, when encounters any object in between the transmitter and the receiver, does not transmit the IR signal to the receiver. This change in the output of the IR receiver will be recognized by the microcontroller and it automatically increments the object count by 1.
