The TCRT5000 Infrared Reflective IR Photoelectric Line Tracking Sensor Module utilizes the TCRT5000 infrared reflective sensor to detect differences in surface reflectivity. It emits infrared light and measures the reflected signal, allowing it to distinguish between black and white surfaces with high accuracy.

The module features an onboard comparator (LM393) that provides a stable digital output and includes an adjustable potentiometer for setting the detection sensitivity. Its compact design and fast response make it ideal for robotics, automation, and educational electronics projects.

Whether you’re building a line-following robot, an automated guided vehicle (AGV), or an obstacle detection system, the TCRT5000 sensor delivers reliable and precise performance.
