TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

While PIR sensors can be used with Arduino and other microcontroller boards, those best-suited for hobby use are smart enough to perform simple tasks without any programming.

The motion sensor feature activates from a 10-foot range, eliminating the need to turn your overhead lights on and off.

If there's a spot in your home that could benefit from some addition lighting, consider these rechargeable motion sensor lights.

Blinding light, guiding light, or something in between, the best outdoor motion sensor lights make sense as a home accessory.

An outdoor motion sensor light offers security and illumination. Our home security expert recommends six models, including battery- and solar-powered lights.
