The goal of the capacitive liquid sensor is to measure the change in capacitance or charge between two metal plates depending on the material between them, making it safe to use with any liquid. The ...

If you’re building an omniscient home-automation system, it’s ability to make decisions is only as good as the input you give it. [Petewill]’s self-made panopticon now knows when someone is in bed.

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...

In a world increasingly dominated by touchscreens, a London design studio is taking an approach to touch that's both low(er)-tech and innovative at the same time. Bare Conductive raised over ...

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 your finger. Created by the team at Willpower ...
