Whadda Line tracking sensor tcrt5000 module

The Line Tracking Sensor based on TCRT5000 is a type of infrared reflectance sensor. It is commonly used in line following robots. It is mounted at the bottom of the robot chassis. The line tracking sensor works by detecting reflected light coming from its own infrared LED and by measuring the amount of reflected infrared light. It can detect transitions from light to dark (lines) or even objects directly in front of it., Fabricante: Velleman
