3-Way Infrared Line Tracking Sensor Module (3-Channel IR Line Follower, 3.3V-5V, Digital Output)

The 3-Way Infrared Line Tracking Sensor Module is a compact optical sensing board designed to detect contrast differences on surfaces for line-following and path detection applications. It integrates three infrared emitter and receiver pairs arranged in a row to detect black lines on white surfaces or white lines on dark surfaces. Each sensor provides an independent digital output, enabling accurate real-time line tracking for robotics and automation projects. Compatible with Arduino, ESP32, ESP8266, STM32, Raspberry Pi, PIC, and other microcontroller platforms, this module is ideal for line-following robots, maze solvers, autonomous vehicles, and educational electronics.
