IR (InfraRed) proximity sensor / Obstacle detector circuit ...

So we adjust the potentiometer so as to make the voltage at inverting input more than non-inverting. When any object approaches the IR proximity sensor, the voltage at photodiode increases and at some point the voltage at non-inverting input becomes more than inverting input, which causes OpAmp to turn on the LED. In the same manner, when the object moves farther from the IR proximity sensor ...

Arduino lesson – IR Track Sensor «

28/08/2018· The IR emission tube of track sensor constantly emits infrared light. Since the black absorbs light, when the IR emission tube shines on a black surface, the reflected light is less and so less IR rays are received by the receiving tube. It indicates the resistance is large; then the comparator outputs high and the indicator LED goes out. Similarly, when it shines on a white surface, the ...
