Having recently moved into a new home, I wanted to set up HomeKit lights in the kitchen that would turn on and off automatically. Ideally. So I got some Philips Hue bulbs, an Eve motion sensor ...

This project solves that problem by hooking up LED lights beneath a bed, then triggering them with a motion controller and an Arduino.

If you can install a conventional outdoor light fixture, you can install a motion sensor light, although aiming and adjusting it takes extra effort.

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada.

The sensor does have some limits. It can only detect motion up to about 16.5 feet away. And while Philips will give you the option of reducing that — that is, only turning on lights when motion ...
