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 ...

It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards which ...

Arriving home to a dark house with an armful of anything is usually an exercise in fumbling confusion until someone manages to turn on a light. [Pavel Gesyuk] has circumvented this problem entirely by ...

If you’ve always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your ...

The Hue Outdoor Sensor is the first outdoor HomeKit sensor, and adds motion, temperature, and light sensors to automate the outside of your Apple-centric smart home. Recently, we took a look at the ...

The Philips Hue line of lights have been controllable via an indoor motion sensor for some time, but Signify is today introducing an Outdoor Motion Sensor that's designed to control the range of ...

Kangaroo’s latest motion sensor adds entry detection to the mix, but its lack of geofencing capabilities or support for any type of security camera makes it tough to recommend. It’s one thing to snap ...
