Treedix 10pcs Obstacle Avoidance Sensor Module Infrared Pair Tube Module Photoelectric Reflection Sensor Compatible with Arduino Smart Car Robot

Features:· The sensor module has strong adaptability to ambient light. It has a pair of infrared emitting and receiving tubes. The emitting tube emits a certain frequency of infrared rays. When the detection direction encounters an obstacle (reflecting surface), the infrared rays are reflected back by the receiving tube receive;· After processing by the comparator circuit, the green indicator light will light up, and the signal output interface will output a digital signal (a low-level signal). The detection distance can be adjusted through the potentiometer knob, and the effective distance range is 2 to 30 cm；· The product has convenient installation, long service life, good conductivity and corrosion resistance;· The detection distance of the sensor can be adjusted by a potentiometer, which has the characteristics of low interference, easy assembly, and convenient use; the working voltage is 3.3V-5V;· It can be widely used in many occasions such as robot obstacle avoidance, obstacle
