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 ~ 30 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
There is an obstacle, the green indicator light on the circuit board
Detection distance: 2 ~ 30cm
Detection angle: 35 °
Comparator chip: LM393
3mm screw holes for easy mounting
ALSO SEARCHED AS:
IR PROXIMITY SENSOR, OBSTACLE AVOIDANCE SENSOR, TSOP SENSOR MODULE
