Makers and developers looking for a motion sensor Arduino Shield, are sure to be interested in this new ICU-Duino which has been created by Patrick Thomas Mitchell based in Ottawa, Canada ...

Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by your desk or into a room. It's completely open source and the notifications system runs on your ...

A passive infrared motion sensor is used to detect the motion of the user’s hand in front of the clock. While all kinds of clocks and clock radios are available out there, few are motion activated.

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 ...

For his sensor, [Felix] is using a Moteino, a very tiny Arduino compatible board with solder pads for an RFM12B and RFM69 radio transceivers.

How it works: When something triggers the sensor, the Arduino records that moment as triggerTime in Line 23, and compares it with the current time based on conditions in lines 26, 29, and 34.

Philips Hue has a new accessory that’ll make it even easier to automate the lighting in your home: a motion sensor. This is, of course, a very standard add-on for home lighting — which is what ...
