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 ...

Makers and hobbyists that are looking for a capacitive touch sensor for a project, might be interested in a new touch sensor board called the EasyTouch. The EasyTouch capacitive touch sensor can be ...

Candle clocks were once an easy way to build a clock without using complex mechanical devices: just observe how quickly a thin candle burns down, mark an identical candle with periodic gradations, and ...

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 ...

While fixed-function capacitive-sensing solutions can ease some of these design burdens, those devices are rarely pure drop-in solutions, as many still rely on developer-side configuration and ...

Capacitive sensors are typically cost-effective and deliver low-power performance features aligned with today’s trends for consumer and industrial applications. Capacitive sensors are cost effective ...

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 ...

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, ...
