In the Maker Shed: PIR Sensor


The PIR sensor, from the Maker Shed, is a great way to add motion sensing capabilities to your project. It uses an infrared sensitive element enclosed by a Fresnel lens to detect changes in heat patterns up to 20 feet away. The simple 3-pin connection lets you easily create alarm systems, motion activated lighting, security cameras, or anything else that needs to sense movement.


The Maker Shed is brought to you by Maker Media, the makers of MAKE Magazine, the Maker Faire, and much more.

Launched originally as a source for back issues of MAKE Magazine, the Maker Shed expanded rapidly to meet the demand for 'projects in a box,' otherwise known as kits. Now we have a little bit of everything for makers, crafters, and budding scientists, from Arduinos to sock monkeys to chemistry sets .
