IR Sensors, Obstacle avoider sensor module

Description

In this Infrared or IR Sensor Module both IR LED and photodiode are placed together. The IR LED in the IR sensor module emits continuous IR waves. These waves move in a straight direction and collide with any object and roll back, and then the photodiode accepts these waves. Thus the IR sensor is used to detect whether or not an object is in front of it.
However, it’s important to keep in mind that the IR sensor does not detect a black surface.
