4. PIR Motion Sensor Motion sensing is useful for a range of applications, from intruder detection to home automation. PIR motion sensors use infrared light to detect movement.

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

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 ...

The Leap Motion controller is a rather impressive little sensor bar that is capable of generating a massive 3D point cloud and recognizing hands and fingers to allow for gesture control based ...

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

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.

Arduino enthusiasts looking for a new project to keep them busy this weekend may be interested in a new slow motion frame which has been created by ...

The accelerometer uses sensors to detect the motion and speed of your hand, while the connected Arduino board will pick up on your motions and work out the commands.

Finger Bend is a unique DIY Arduino powered textile flex sensor, created as part of the Swatch Exchange, enabling you to trigger actions by simply bending ...
