☆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.
