Sharp GP2D120 Infrared Sensor

The GP2D120 infrared sensor takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 4cm (1.5") to 30cm (11.8").

The interface is 3-wire with power, ground and the output voltage.

Simply provide power and ground, and read a continuous analog voltage representing distance. A software lookup table can be implemented to translate the voltages to distances.

Don't forget to add the optional accessories below!
