TCRT5000 Infrared Reflectance Obstacle Sensor Module

Description

The reflectivity of infrared light varies with the color and distance of the reflecting surface. According to this principle, this IR Reflective Sensor utilizes a TCRT5000 reflective photosensor module to detect color and distance.

When a light-colored object approaches, the signal intensity received by infrared reflective sensor increases and the indicator LED on board turns red. When a dark-colored object approaches, the intensity decreases and the LED turns off.

This sensor is a basic and widely used part in applications such as line-following cars, rotary speed detection, auto data logging on utility meters or other situations where color or distance contrast is sharp.
