The Sharp - GP2Y0A21YK0F is a distance measuring sensor, composed of an integrated combination of PSD (position sensitive detector), IRED (infrared emitting diode), and a signal processing circuit. The environmental temperature and the operating duration are not influenced easily on 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.
Note: In the Sharp sensors there are different models, with each model comes a different sensing range. Surf our website to find the sharp sensor that suits your project
