Line Tracker (Finder) Sensor

This is high performance line finder that is designed for line following robotic. It consists two parts - an IR emitting LED and an IR sensitive phototransistor. It can output digital signal to a microcontroller so the robot can reliably follow a black line on a white background, or vice versa. The sensor is Arduino compatible. Feature Small size. 5V DC power supply. Indicator LED. Digital output. Distance: up to 3 cm Pin Definition GND: Ground DO: Output Digital AO : output Analog VCC: 3.3-5 VDC For Arduino code to use the line finder sensor, please click here
