ARDUINO Accessory, Sharp GP2Y0A21YK0F, GO2YOA21YKOF, Distance Sensor 10-80CM, Range Module for Arduino, IR Infrared

Features: Distance measuring range: 10 to 80 cm Analog output type Consumption current:. Typ 30 mA Supply voltage: 4.5 to 5.5 V Specification: GP2Y0A21YK0F is a distance measuring sensor unit, composed of an integrated combination of PSD (position sensitive detector), IRED (infrared emitting diode) and signal processing circuit. The variety of the reflective of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor.
