Line Following Sensor for Arduino – Reflectivity Detection Made Simple

Easy Line Tracking for Your Arduino Projects

The Reflectivity / Line Following Sensor for Arduino is the perfect solution for adding line tracking and reflective surface detection to your DIY projects. Designed for beginners and hobbyists, this sensor module makes it easy to build a line following robot or monitor wheel rotation using your Arduino.

How the Reflectivity Sensor Works

This module uses an infrared emitter and detector pair to sense how much light a surface reflects. When the reflected light intensity passes a set threshold, the sensor outputs a digital HIGH signal. The sensitivity is easily adjustable with the onboard potentiometer, letting you fine-tune the sensor for different surfaces or lighting conditions.

Simple Arduino Connection

Connecting the line following sensor is straightforward. Just use three wires: V+ (5VDC), GND, and a digital output pin on your Arduino board. The module uses the reliable LM393 comparator chip to ensure accurate and stable detection.
