Seeed Grove - Infrared Reflective Sensor 4.5-5.5V

Seeed Studio

The Grove - Infrared Reflective Sensor from Seeed Studio allows your Pi or Arduino to sense the brightness reflected from a surface. This can be applied to sensing the presence or absence of an object, for example whether a door is open or closed or maybe as a contactless end-stop for a CNC machine. Or it can be used to detect changes in brightness such as black and white markings on a rotating disc. A very useful sensor.\n\n--Operating voltage: 4.5 to 5.5V DC\n-- Digital output, 0 or Vcc\n-- High resolution sensor; min. detectable width: 1mm black line\n-- Effective distance:4 to 15mm\n-- Indicator LED on board\n-- Sensitivity adjustable via potentiometer\n-- Small Grove 1X1 compatible interface\n\n--\nOur eBay Store\n\nSeeed 101020174 Grove - Infrared Reflective Sensor 4.5-5.5V\n\nProduct Details\n\nThe Grove - Infrared Reflective Sensor from Seeed Studio allows your Pi or Arduino to sense the brightness reflected from a surface.
