Infrared obstacle avoidance module

Share to:
The infrared obstacle avoidance sensor module has strong adaptability to the ambient light. It has a pair of infrared transmitting and receiving tubes. The transmitting tubes emit infrared rays of frequency. When the detection direction encounters an obstacle (reflecting surface), the infrared rays are reflected back and received by the receiving tube. After being processed by the comparator circuit, the red indicator light will light up, and the signal output interface outputs a digital signal (a low-level signal), The detection distance can be adjusted through the potentiometer knob. The effective distance range is 0 ~ 20cm. Adjust the potentiometer clockwise to increase the detection distance, and adjust the potentiometer counterclockwise to reduce the detection distance.

Product introduction

The infrared obstacle avoidance sensor module has a strong ability to adapt to the environment light. It has a pair of infrared emitter and receiver tubes, which emit infrared of frequency. When the direction of detection encounters obstacles (reflector), the infrared reflector returns to be received by the receiver tube. After the comparator circuit processing, the red indicator lights up, and the signal output interface outputs a digital signal (a low level signal). The detection distance can be adjusted by the potentiometer knob, the effective distance range is 0~20cm, the clockwise potentiometer can increase the detection distance, and the counterclockwise potentiometer can reduce the detection distance.

The sensor has the characteristics of small interference, easy assembly and easy use. It can be widely used in many applications such as obstacle avoidance, obstacle avoidance car, pipeline counting and black-and-white line tracing.
