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 ...

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 ...

If you’ve got an existing smart home rig, motion sensors can be a useful addition to your setup. You can use them for all ...

Need a cheap and easy way to deter intruders? For homeowners, outdoor lighting is a game changer for providing a line of sight on potential trepassers without running up costly energy bills. If you're ...

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 ...

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 ...
