Description
4 Channel Infrared Line Follower Sensor Module
The basic concept of 4-Channel Infrared IR Line Follower 4 Way Transmission Line Sensor Arduino is to transmit the IR signal (radiation) in a direction and a signal is received at the IR receiver when the IR radiation bounces back from a surface of the object.
This 4 channels IR reflective sensor includes 4 IR sensors and main board to handle all the signals. Each IR reflective sensor is composed of an IR emitter and a receiver, if something is in the measuring range, the sensor would outputs related signal. There are also 4 potentiometers on the main board so that the measuring range can be adjusted as you wish.
