4 Channel Infrared Tracking Sensor Module IR Line Tracker

Smart car or a robot hunt (including black and white lines), walking path along the black line, also known as tracking. Smart car to avoid obstacle and cliff, anti-drop. Can be applied to other automation applications of photoelectric reflex.

Features:
Working voltage: DC 3.3V-5V
Working current: try to choose more than 1A power supply
Working temperature: -10°C to +50°C
Mounting aperture: M3 screw
Detection range: 1mm to 60cm adjustable, the closer the performance more stable, white reflects the farthest distance.
Output interface: 6 wire interface (1234 to 4 signal output ends, + positive power, – for the negative power is ground)
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.)
