How IR Sensor Works

As we give power to IR Sensor using Arduino at that time White LED light is transmitted the IR rays. This IR ray is strike with the thing , it’ll reflect back and received at black LED light.

As this phenomenon occur IR Sensor Produce Low or High Voltage at output pins. It depends on what kind of sensor you select .
Your Programming is trusted which type of sensor you decide on .
So you’d like to ascertain it out.

  • Active High Sensor : Output is High
  • Active Low Sensor : Output is Low
