Object Counter Using Ir Sensor. Arduino is a microcontroller-based open source electronic prototyping board which can be. In this circuit we have used a comparator IC LM358 and IR transmitter and receiver pair for detecting a object. Objects would be dropped onto a ramp it would roll down into a container at the bottom but will be detected by a pair of IR detectors. Here the IR Sensor is used to detect the object as there a program is being continuously running in a loop.
The circuit diagram of object counter is quite similar to my previous project digital stopwatch circuit but a little complex. The output of the Photodiode will go through a NOT gate and then into the comparator. 555- configured in monostable mode automatic dark sensor using 555 2. Void setup put your setup code here to run once. Today we are about to see building of simple Visitor counter project using Arduino which uses IR as a tool for sensing people. The TCS3200 color sensor is used to sense a wide range of colors.
The output of the Photodiode will go through a NOT gate and then into the comparator.
The counter stops counting if the IR rays is continuously falling on the IR sensor. For example it can be used at the railway stations or bus stands to count the people arriving per day or week. As soon as an object obstructs the IR signal the counter immediately counts the interruption. Void setup put your setup code here to run once. The light will be off and start again.
