4-channel line tracing/follower sensor for Arduino
Features:
- Operating voltage: DC 3.3V-5V
- Operating Current: try to choose more than 1A power supply
- Operating Temperature: -10 ° C - +50 ° C
- mounting aperture: M3 screw
- detection distance: 1mm to 60 cm
- adjustable closer the performance is more stable, the white reflection farthest.
- The output interface: 6-wire interface (1234 for the 4-way signal output terminal, + positive power, - the negative power supply is ground) Output signal: TTL level (directly connected microcontroller I / 0, sensitive to infrared light reflected back by the sensor, the red light is on, the output low; absence of infrared light, the light does not shine, the output high level.)
- Applications: A smart car or robot hunt (including black and white lines), walking along the path of the black line, also known as tracing. Smart car to avoid the cliff, anti-drop. Smart car for obstacle avoidance
