Infrared proximity sensor made by Sharp. Part # GP2Y0A02YK0F?hasan analog output that varies from 2.8V at 15 cm to 0.4V at 150 cm with a supplyvoltage between 4.5 and 5.5VDC. The sensor has a Japanese Solderless Terminal(JST) Connector. We recommend purchasing the related pigtail below or solderingwires directly to the back of the module.
This sensor is great for sensing objects up to 5 feet away!
GP2Y0A02YK0F is a distance measuring sensor unit, composed of anintegrated combination of PSD (position sensitive detector) , IRED (infraredemitting diode) and signal processing circuit. The variety of the reflectivityof the object, the environmental temperature and the operating duration are notinfluenced easily to the distance detection because of adopting thetriangulation method. This device outputs the voltage corresponding to thedetection distance. So this sensor can also be used as a proximity sensor
