4 Channel Infrared Tracing Module

Features-

1. Detection range: 1mm to 60 CM adjustable, the closer the performance more stable, white reflects the farthest distance.
2. Size: in the control panel:42 x 38 x 12mm (length x width x height).
3. Small forward: 25 x 12 x 12mm (length x width x height).
4. Output interface: 6 wire interface (1234 to 4 signal output ends, + positive power, – for the negative power is ground)
5. The output signal: TTL level (can be directly connected to I/0 microcontroller, infrared light 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.)
