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

Product Information Accessory Type: Infrared Reflective Sensor Board For Use With: Arduino Board Product Range: - Product Overview 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. Panel-mounting grove interface Built-in indicator LED Threshold adjustable via potentiometer Reflective Photosensor: RPR-220 Effective working distance: 4-15mm Minimum detectable width for monochrome lines: 10mm 4 pin buckled grove interface
