Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

From Disney World to the smartphone in your pocket, fingerprint scanners have become commonplace these days. Even budget phones sport the tech, sometimes alongside other biometric unlocking options ...

Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

Many billions of mechanical buttons in cell phones, cars audio systems, notebooks, PCs, white goods, and industrial applications have been replaced with capacitive sensing buttons. The use of ...

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 ...

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 ...

Engineers developing heavy equipment such as tractors, cranes, wood chippers, and construction equipment need to include incline sensors and indicators—both to ensure that workers do not operate the ...
