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 ...

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 ...

We’re still not sure exactly how [connornishijima]’s motion detector works, though many readers offered plausible explanations in the comments the last time we covered it. It works well enough, though ...

You don't need expensive software or a new camera to keep an eye on things at home. Whether you're looking after your dog or trying to catch burglars in the act, you can put together a home security ...

ST’s ISM6HG256X three-in-one motion sensor combines simultaneous low-g and high-g acceleration detection with a precision gyroscope.

You'll typically find motion detection capabilities confined to cameras in most home security systems, but the Philips-backed Signify is keen on imbuing luminous products with the tech. The company ...

KickStarter is the launch pad for some of the most exciting products we've seen for cyclists, and this latest project called Bike Luminance is definitely one of the cooler ones. Using a motion sensor ...
