Specifications: 1 Operating Voltage: DC 3.3~5V

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

3 Working temperature: -10~+ 50'C

4 Install Aperture: M3 screws

5 Detection distance: 1mm to 60cm adjustable, the closer, the more stable performance, white reflective distances is the furthest

6. Size: control panel: 4.4mm x 4.0mm x 12mm (length x width x height); Small plates forward: 25mm x 12mm x 12mm (length x width x height)

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

8 Output signal: TTL level (which can be directly connected to the microcontroller I / No. 0, sensitive to infrared light reflected from the sensor, the red light is on, the output low; no infrared light, the light is not bright, high power output level.)

Applications: 1 Smart car or robot hunt (including black and white lines), walking along the black line path, also known as tracing. 2 Smart car to avoid the cliff, anti-fall.
