Description: Infrared proximity sensor made by Sharp. Part # GP2Y0A02YK0F has an analog output that varies from 2.8V at 15cm to 0.4V at 150cm with a supply voltage between 4.5 and 5.5VDC. The sensor has a Japanese Solderless Terminal (JST) Connector. We recommend purchasing the related pigtail below or soldering wires directly to the back of the module.
This sensor is great for sensing objects up to 5 feet away!

The analog signal from this sensor is working quite well with my Arduino. I use this sensor to indicate when I am at my desk. The desk is positioned such that my wife can’t see me sitting there. The Arduino activates a “Christmas” star ornament positioned on the top of a hutch located on the desk. This sensor is replacing an incandescent thru beam sensor that has a history of burned out bulbs due to heat. This sensor has great range and was easy to setup.
