The TCRT5000 are reflective sensors, which include an infrared emitter and phototransistor in a leaded package, which blocks visible light. The package includes two mounting clips. The Arduino TCRT5000 is designed to sense the distance to an object using Infra Red light waves. It can also identify the difference between white and black based on the contrast of an object and it’s reflective properties.
