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 ...

The IoT continues to influence and modernize products for home and building automation. Although this market is expected to grow significantly, its potential depends on how users adopt these products, ...

The sensors provide a reliable alternative to mechanical switches that may have a high rate of wear and tear. The sensors use capacitive technology for start and stop actuation, and are available with ...

Capacitive touch sensing has been traditionally used as a design differentiating technology to enable superior aesthetic designs for automotive infotainment applications. With devices maturing to the ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...
