Infrared Reflective Sensor utilizes a RPR220 reflective photosensor module to detect distance. When a reflective object approaches,the signal intensity received by infrared reflective sensor increases and the indicator LED on board turns red.
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.
