TCRT5000 IR Reflective Sensor Module

TCRT5000 Reflective Optical Sensor Breakout Module

The TCRT5000 integrates an infrared emitter and a phototransistor in a leaded package that blocks visible light. Mounted on an LM393 comparator board with potentiometric sensitivity adjustment, it detects black/white surface contrast for line-following robots.
