TCRT5000 IR Reflective Sensor | Line Tracking & Object Detection Sensor

The TCRT5000 Infrared Reflective Sensor is a commonly used proximity and line-detection sensor in robotics. It works by emitting infrared (IR) light and measuring the reflected light from nearby surfaces. Based on reflection intensity, it can detect black/white lines, edges, and nearby objects.
