Infrared Reflectance Switch Infrared Sensor Module Smart Car
Function features
1. On-board LM393 voltage comparator chip and infrared sensor probe
2. Supported 5V / 3.3V power supply
3. The output signal is active low and the indicator LED will on,it’s can be connect to the MCU I/O directly
4. The sensitivity of signal detection can be adjusted
5. With 3mm screw holes, easy to install
6. The detection distance range is 1 ~ 25mm. It can be adjusted by the potentiometer, clockwise regulation is decrease, and anticlockwise is increase
