4 Channel Infrared Detector Tracked Photoelectricity Sensor

Description : • Working voltage: DC 3.3V-5V • Working current: try to choose more than 1A power supply • Working temperature: - 10oC - +50oC • Mounting aperture: M3 screws • Detection range: 1mm to 60 CM adjustable, the closer the performance 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 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.) • A Smart car or a robot hunt ( including the black and white lines ) , walking along the black line path , also known as tracing . • Smart car to avoid the cliff , anti- fall. • Smart car to avoid obstacles
