Infrared Proximity Sensor Long Range – Sharp?GP2Y0A710K0F?isa distance measuring sensor unit, composed of an integrated combination of PSD(position sensitive detector) , IRED (infrared emitting diode) and signalprocessing circuit. The variety of the reflectivity of the object, theenvironmental temperature and the operating duration are not influenced easilyto the distance detection because of adopting the triangulation method. Thisdevice outputs the voltage corresponding to the detection distance. So thissensor can also be used as a proximity sensor.
This sensor takes a continuous distance reading and reports thedistance as an analog voltage with a distance range of 100 cm to 550 cm. Theinterface is 3-wire with power, ground and the output voltage.
