The KY-033 Tracking Sensor Module is an infrared (IR) reflective sensor designed to detect black and white surfaces for line-following robots and electronic projects. It uses an infrared emitter and receiver to detect differences in reflected light, allowing a connected microcontroller to identify a line or track a path.

This compact sensor module is ideal for Arduino-based robotics, autonomous vehicles, and educational electronics projects. It provides a digital output signal that can be used by a microcontroller to control motor movement according to the detected surface. Its adjustable sensitivity allows users to fine-tune detection performance for different operating conditions.
