10pcs IR Infrared Obstacle Avoidance Sensor Module for Smart car Robot 3 Wire Photoelectric Reflection Sensor

What is IR infrared obstacle avoidance sensor module?The sensor module has strong adaptability to ambient light. It has a pair of infrared transmitting and receiving tubes. The transmitting tube emits infrared rays of a certain frequency.When the detection direction encounters an obstacle (reflective surface), the infrared rays are reflected back and received by the receiving tube. After processing by the comparison circuit, the green indicator light lights up, and the signal output interface outputs a digital signal (low-level signal). The detection distance can be adjusted through the potentiometer knob.Product Parameter：1. The effective distance range is 2~30cm, and the working voltage is 3.3V-5V.2. It has 3mm screw holes for easy fixing and installation.3. Circuit board size: 3.2CM*1.4CMModule Interface Description：✔VCC external 3.3V-5V voltage (can be directly connected to 5v microcontroller and 3.3v microcontroller)✔GND external GND✔OUT small board digital output interface (0 and 1)Package Included：10x IR infrared obstacle avoidance sensor module
