Specifications:

1. Working voltage: DC 3.3V-5V

2. Operating Current: try to choose more than 1A power supply

3. Working temperature: -10 ° C - + 50 ° C

4. Install Aperture: M3 screw

5. Detection distance: 1mm to 60 CM adjustable, the closer the more stable performance, a white reflective distances.

6. Size: the control board 42mm × 38mm × 12mm (length × width × height)

           Small plate forward 25mm × 12mm × 12mm (length × width × height)

7. Output Interface: 6-wire interface (1234 4-way signal output, + for the positive power supply, - for the negative supply that is ground)

8. Output signal: TTL level (can be directly connected to the microcontroller I / 0, the sensor sensing the reflected infrared light, red light is on, the output low; when no infrared light, the light does not shine, high output power level.)
