## Description

This is an [Arduino](https://core-electronics.com.au/arduino.html) infrared [distance sensor](https://www.dfrobot.com/category-55.html). It has an adjustable detection range, 3cm - 80cm. It is small, easy to use, assemble, and inexpensive.

Useful for [robotics](https://www.dfrobot.com/category-37.html), interactive media, industrial assembly line,etc. Infrared wave length is part of the Sun's natural light spectrum. While is a nice fit for indoor projects, outdoors with plenty of sun light and reflective surfaces on it's sight is not adviced. It's incredibly repurposable and canbe used for a lot of different projects. The adjustable screw on it's back makes it very convenient for different purposes. After digital read shows on your [Arduino](https://core-electronics.com.au/arduino.html) pin andthen you are ready to go. It is a great sensor choice for quick[ prototyping](https://core-electronics.com.au/prototyping.html).

Use it on a [robot](https://www.dfrobot.com/category-37.html) for wall detection and wall follower, or as some of the [projects](https://www.dfrobot.com/category-projects.html) listed below as atrigger 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 nearyour PC to turn on and off your monitor.

To ease the difficulty, a [Gravity ](https://core-electronics.com.au/gravity)Interface is adapted to allow plug&play. The [IO expansionshield](https://www.dfrobot.com/product-1009.html) is the best match for this [sound senor](https://www.dfrobot.com/category-63.html) connecting to your [Arduino](https://core-electronics.com.au/arduino.html).
