4 Ways Infrared Tracking Line Following Module Sensor for Arduino Specifications: 1. Working voltage: DC 3.3V-5V 2. Operating Current: try to choose more than 1A power supply 3. Working temperature: -10 ° C - + 50 ° C 4. Install Aperture: M3 screw 5. Detection distance: 1mm to 60 CM adjustable, the closer the more stable performance, a white reflective distances. 6. Size: the control board 42mm × 38mm × 12mm (length × width × height) Small plate forward 25mm × 12mm × 12mm (length × width × height) 7. Output Interface: 6-wire interface (1234 4-way signal output, + for the positive power supply, - for the negative supply that is ground) 8. Output signal: TTL level (can be directly connected to the microcontroller I / 0, the sensor sensing the reflected infrared light, red light is on, the output low; when no infrared light, the light does not shine, high output power level.) Applications: 1. smart car or a robot hunt (including black and white lines), walking path along the black line, also known as tracking. 2. Smart car to avoid the cliff, anti-drop. 3. Smart car to avoid obstacles
