1. Detection distance of the module is 2~30cm, the detection angle is 35°, and the detection distance can pass. The potentiometer is adjusted, the potentiometer is adjusted clockwise, the detection distance is increased, and the potentiometer is adjusted counterclockwise to reduce the detection distance.

2. its output port OUT can be directly connected to the MCU IO port, or it can directly drive a 5V relay; connection mode: VCC-VCC; GND-GND; OUT-IO

3. The comparator: LM393;

4. Operating voltage 3.3V-5V

5. Circuit board size: 3.2CM * 1.4CM
