4-channel infrared line follower sensor

Easily build your first linear robots with this handy 4-channel line follower sensor. It includes all the accessories and cables necessary to put it to work. Infrared sensor module is used to prevent obstacles, in intelligent cars, robots and automatic machine provides a multifunction infrared detection system for the automatic machine adopts the infrared transmitter and receiver and the components as detector has 4 channels Voltage of operation is 3.3V - 5V DC Features: Working Stream: Try to choose more from the power supply 1A Working temperature: - 10 ° C - 50 ° C + Mounting opening: M3 screws Detection range: 1 mm to 60 cm Adjustable, the closer the performance closer the more Stable, white reflects the farthest distance. Size: on the 42mm*38mm*12mm control panel (length*width*height)small 25mm forward*12mm*12mm(length*width*height) Output interface:6 wire interface (1234A 4 signal output ends, positive power +, - by the negative power is ground) the output signal: TTL level (can be connected directly to the I/0 microcontroller, the infrared light reflected back to the sensor induction, the red indicator light, low output Level; no infrared light, the indicator light does not shine, the high output.)
