The Arduino was in turn connected to the serial port of an unused Ericssson T10s mobile phone. This allows the Arduino to call his mobile phone whenever the motion detector senses movement.

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 whi… ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go.

A gangly-looking motion detector floodlight is fine for scaring off a backyard intruder, but it doesn't look good on your house. A remote-style motion detector is a better choice. You can connect ...

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 ...

Turn on then off Turn on/off it motion detected (this one obviously requires the motion-detector) This rather basic-sounding set of rules is surprisingly powerful. Let’s take an example.

Want to control your lights at home from across the globe? The Belkin WeMo Switch + Motion provides a simple entryway into the world of home automation.

IFTTT, or "If This Then That", has overhauled its rule-based automation site with a new design, new channels, Quick Triggers, and Belkin WeMo compatibility.

Plug a light or an appliance into the WeMo, then pair it your smartphone and switch your electronics on and off without leaving the comfort of your bed.
