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.
