IR Line Tracking Sensor Module – Adjustable Sensitivity

The IR Line Tracking Sensor Module is designed for detecting lines and surface contrast in mobile robotics and automation projects. It operates using infrared reflection, where an IR emitter and receiver detect differences between light and dark surfaces. The module features both analog and digital outputs and an onboard potentiometer for sensitivity adjustment. Built for stable operation at 3.3V or 5V, it integrates easily with microcontrollers such as Arduino UNO, ESP32, and Raspberry Pi Pico. Ideal for line-following robots, automation systems, and educational robotics experiments.
