<br />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 reflectivity of the object, the environmental temperature and the operating durationare not influenced easily to the distance detection because of adopting the triangulation method. This device outputs the voltage corresponding to thedetection distance. So this sensor can also be used as a proximity sensor.
<br />Package included:
<br />1  x  GP2Y0A21YK0F IR Analog Distance Sensor with 10-80CM Cable For Arduino
