• 4 channel infrared tracking sensor module ir line patrol for arduino smart car feature: 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.

SPECIFICATION:

• 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. )
