4 Channel Infrared Tracing Module

Specifications:

Working voltage: DC 3.3V-5V

Working current: try to choose a power supply above 1A

Working temperature: - 10oC - + 50oC

Mounting hole: M3 screws

Detection range: 1mm to 60cm adjustable, the closer the performance is more stable, white reflects the farthest distance.

Size: in the control panel of 42mm * 38mm * 12mm (length * width * height)

Small forward 25mm * 12mm * 12mm (length * width * height)

Output interface: 6-wire interface (1234 to 4 signal outputs, + positive power, - for the negative power is ground)

The output signal: TTL level (can be directly connected to the I / 0 microcontroller, infrared light is reflected back to the sensor induction, the red indicator light, output low level; no infrared light, the indicator light does not shine, the output high.)
