The sensor module light is adaptable to the environment, the working voltage of 3.3 V to 5 V.;It has a pair of infrared transmitting and receiving tube, when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving by the tube.;After the comparator circuit processing, green indicator will light up, at the same time the signal output interface output a digital signal (a low level signal), can be adjust the detection distance through the potentiometer knob, effective distance range 2 ~ 80 cm, easy to assemble and use. So it can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and so on many occasions.
