Researchers at the Georgia Institute of Technology have created a passive motion/contact sensor that detects motion using ...

It’s really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For literally a couple of dollars you can get a decently powerful Wi-Fi enabled microcontroller ...

The presented schematic shows how to build a simple PIR motion sensor. PIR sensors allow motion sensing, it is almost always used to detect whether someone has moved in or out of the sensors range.

Halloween is coming up faster than you think: time to dust off the gravestones and the zombie lawn decorations! This year you may want to add a little something extra to give the trick-or-treaters a ...

Researchers at the Georgia Institute of Technology have built a motion and contact sensor ...

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 ...

EPFL scientists have now developed an extremely sensitive yet simple motion detector that can be built easily by adapting already-existent technology. The system has proven accurate with detecting ...

Your garden variety motion detector uses IR, but these days, there are fancier technologies for achieving similar goals. If so desired, you can source yourself a microwave-based presence sensor ...
