Line finder sensor is infrared tracking sensor module and it 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.
Features:
- Arduino UNO R3 and the compatible board can directly connect to this module.
- Working voltage: 4.7-5.2VDC
- Digital output: TTL (High level when black is detected, low level when white is detected)
- On-board potentiometer: adjust the sensitivity.
- On-board indicator LED.
- Applications: Smart Car, Tracking Robot
