About Infrared Proximity Sensor Module

The infrared Proximity Sensor Module has a pair of infrared transmitting and receiving tubes. When the transmitted light waves are reflected back, the reflected IR waves will be received by the receiver tube. The onboard comparator circuitry does the processing and the green indicator LED comes to life.

The module features a 3-wire interface with Vcc, GND, and an OUTPUT pin on its tail. It works fine with 3.3 to 5V levels. 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, the effective distance range is 2cm to 80cm.

IR Sensor module has the great adaptive capability of the ambient light, having a pair of an infrared transmitter and a receiver tube, the infrared emitting tube emits a certain frequency, encounters an obstacle detection direction (reflecting surface), infrared is 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 ~ 10cm 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, and can be widely used for robot obstacle avoidance, obstacle avoidance car assembly line count, black-and-white line tracking, and many other occasions.
