INTRODUCTION

This is an Arduino infrared distance sensor. It has an adjustable detection range, 3cm - 80cm.  It is small, easy to use, assemble, and inexpensive.

Use it on a robot for wall detection and wall follower, or as some of the projects listed below as a trigger system. It's round shape with the screwable holders make it a good choice for a home made assembled robot, with a hole of it's diameter and the holders you can place it aiming at different positions on a robot. Or even place it near your PC to turn on and off your monitor.

To ease the difficult of using this sensor,  a Gravity Interface is adapted to allow plug&play.  The IO expansion shield is the best match for this sound senor connecting to your Arduino.
