This voltage can be read by an Arduino digital input and then the Arduino can act upon it. The PIR Motion Sensor on the left is made by Parallax and sold by Radio Shack. The one on the right comes ...

Last year, I took a look at some mostly low-cost passive infrared (PIR) motion sensor modules. Then recently, I became more aware of cheap microwave radar motion sensor modules. The popular version of ...

[Connornishijima] has stumbled on a different way to detect motion with an Arduino, he’s polling an ADC pin with a simple length of twisted pair hooked up to it and earth, and reliably ...

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.

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. If that sounds ...

Electronics hobbyists, experimenters and constructors of microcontroller project frequently need to measure/detect voltage, current, frequency, temperature and… proximity. Most measure ...

The first trick, shown in the video above, is an Arduino-powered squirt bottle that also uses a motion detector to fire rapidly every time there's some motion in front of it. If you're trying to ...

A presence sensor uses wave radar technology to sweep a room, looking for the slightest movement, not the broad gestures that would be caught by a motion sensor. If you're breathing, the presence ...
