KY033 is a fairly accurate line tracker that is designed for line following 4 wheels and two wheels moving robotics . It consists two parts: an IR emitting LED and an IR sensitive phototransistor. It can output digital signal to a microcontroller or Arduino so the robot can follow a black line on a white background. The accuracy and detection distance can be adjusted using the onboard poteniometer.
