OBJECT COUNTER WITH 7 SEGMENT DISPLAY


PROJECT DESCRIPTION

The project is designed to monitor the counting operations in industries. For example, products moving on a conveyor belt are counted by IR interruption concept and displayed on a seven segment display.

        There are two pair sensors, each kept at certain distance from the other. One pair of sensor consists of a transmitter and a receiver, kept exactly opposite to each other. The transmitting part emits modulated IR light which is received at the receiver end and fed to a microcontroller of 8051 family. When an object passes through the sensors then microcontroller gets interrupt signal (from IR sensors) and increments the count to displays it on 7 segments displays. Count down is also achieved if the object moves in reverse direction. This project can also be used in any public transport/trains to count the number of passengers for monitoring purpose.
