The SHARP distance sensor uses infrared reflection to measure distances from 10 cm to 80 cm, outputting an analogue voltage for simple integration, and includes a 12″ JST cable for quick connection to microcontroller projects.

This SHARP distance sensor bounces IR off objects to determine how far away they are. It returns an analogue voltage that can be used to determine how close the nearest object is. Comes with 12″ long 3-JST interface wire. These sensors are good for short-range detection. For over 1 m distance, we suggest using sonar sensors

To use, connect black wire to ground, red wire to 5V and white wire to analog input. The analogue voltage out will range from 3V when an object is only 4″ (10 cm) away and 0.4V when the object is 32″ (80 cm) away

For more information, please see the Sharp website (link in our resources section). Note that it’s not well documented but the case is conductive! So if you’re mounting to a metal chassis, use a rubber gasket to isolate it.
