In this tutorial we will learn how to working IR sensor. The IR sensor signal is a general purpose proximity sensor. It use for objects detection front of IR sensor.

 

We can watch the video or read the written  tutorial below.






The IR sensor consist IR signal transmitter and IR signal reciver. The IR signal transmitter emit infrared light. The infrared light is not visible of human eye.
The IR signal reciver is recived the infrared light. When the obstacles or surfaces come in front the IR sensor then the infrared light is reflection. The IR signal reciver is recived this infrared light reflection.
