3-Channel IR Line Tracking & Path Detection Sensor Module

The 3 Channel Path Tracing Module is a reflective infrared sensor module designed for line following, path detection, and edge sensing applications. Equipped with three independent IR emitter–receiver pairs, it can accurately detect black/white contrast and guide robots or automated vehicles along a predefined path. The module provides stable digital outputs and is ideal for robotics competitions, DIY robots, educational STEM projects, and automation systems requiring multi-point line tracking.

1. 3 independent IR sensing channels for accurate path detection
2. Stable digital output signals for easy microcontroller interfacing
3. High sensitivity to black/white surface contrast
4. Adjustable detection threshold (potentiometer, on compatible versions)
5. Suitable for line-following robots and automated guided systems
6. Compact and lightweight PCB design
7. Compatible with Arduino, ESP32, Raspberry Pi, and robotic controllers
