IR Distance Sensor-Sharp
This sensor takes a continuous distance reading and reports the distance as an analog voltage with a distance range of 10cm (4″) to 80cm (30″). The interface is 3-wire with power, ground and the output voltage.
How it works: Infrared is sent out by the sensor which bounces off objects. The analog voltage that is returned determines how close the nearest object is. The closer it is, the higher the voltage is returned.
