☆The sensor module has strong ability to adapt to ambient light. It has a pair of infrared transmitting and receiving tubes. The transmitting tube emits infrared light of a certain frequency. ☆Signal output interface outputs a digital signal (a low-level signal). The detection distance can be adjusted by the potentiometer knob. The effective range is 2 to 30cm and the working voltage is 3.3V.5V. ☆The sensor's detection distance can be adjusted by a potentiometer, has small interference, is easy to assemble, and is easy to use. ☆It can be widely used in robots to avoid obstacles, avoid cars, count pipelines, and track black and white lines. ☆Sensor module output port OUT can be directly connected with the microcontroller IO port can also directly drive a 5V relay connection mode: VCC-VCC; GND-GND; OUT-IO.
