Seeed Studio (101020174) Sensor Board, with Cable, Infrared Reflective

Grove - Infrared Reflective Sensor v1.2 can be used for the detection of proximity and colour of objects. The reflective photosensor - RPR-220 used in this module consists of an infrared light emitting diode and a high -sensitivity phototransistor. This sensor is widely used in applications such as line-following robots, rotary speed detection and auto-data logging on utility meters or other situations where colour or distance contrast is sharp.
