IR stands for Infrared which is a light with wavelength which is not visible to human eyes but cameras can see it. In a IR Sensor an IR LED and a Photodiode is used to find a obstacles . The IR LED transmits light in forward direction when an obstacle is ahead the light reflects and the Photodiode is activated by this method Obstacle is detected. It is used in many applications such as TV remote and Night-vision cameras.
