The Microduino Line Finder is an IR reflection sensor module. Since its measuring range is about 3cm, you can use this sensor as a line finder. It can detect black/white and the distance from the obstacle.

Principle of black line detection

• The infrared emitting tube emits light ray to the surface of the road
• The IR light will be reflected when touching the white road
• The receiving tube will receive the reflecting light
