OBJECT COUNTER
WITH 7 SEGMENT DISPLAY
ABSTRACT
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.
Further the project can be enhanced by interfacing it
with a warning system so that if total number of occupants in the vehicle
exceeds the passenger carrying capacity then an alarm is generated by the
device.
