Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

As with traditional mechanical switches, a user's interface experience with a capacitive sensor is directly related to the way the sensor responds (sensitivity) upon contact under all operating ...

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 ...

Non-contact displacement measurements can be made rapidly and with high precision using capacitive sensors over a modest range. The main features are: Capacitive sensing is a non-contact measurement ...

Capacitive sensing provides a robust alternative to traditional mechanical switches. However, some applications cannot accommodate the physical implementation of a printed circuit board directly under ...

Capacitive sensors supply high accuracy at a relatively low cost. But system designers attempting to use them have been forced to first convert the capacitance to a voltage, then convert the voltage ...

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 ...
