5Pcs Infrared Obstacle Avoidance Sensor For Arduino Smart Car Robot

5Pcs Infrared Obstacle Avoidance Sensor For Arduino Smart Car Robot   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. Package included:  5 x Arduino obstacle avoidance sensor
