This sensor module have great adaptive capability of the ambient light, having a pair of infrared transmitter and the receiver tube.
The infrared emitting tube to emit a certain frequency, encounters an obstacle detection direction (reflecting surface), infrared reflected back to the receiver tube receiving, after a comparator circuit processing, the green LED lights up, while the signal output will output digital signal (a low-level signal), through the potentiometer knob to adjust the detection distance, the effective distance range 2 ~ 80cm working voltage of 3.3V-5V. The detection range of the sensor can be adjusted by the potentiometer, with little interference, easy to assemble, easy to use features, can be widely used robot obstacle avoidance, obstacle avoidance car assembly line count and black-and-white line tracking and many other occasions.
The module features a 3 wire interface with Vcc, GND and an OUTPUT pin on its tail. Upon hindrance/reflectance, the output pin gives out a digital signal (a low level signal). The onboard preset helps to fine tune the range of operation, effective distance range is 2 cm to 80 cm.
