The basic idea is that it’s possible to measure a capacitor’s capacitance using ... one digital and one analog. As configured, [mircemk]’s sensor measures roughly thirty picofarads, and ...

Another important development is the creation of high-precision capacitive image sensors that can detect ... including touch screens. Analog Front-End (AFE): The part of a circuit that processes ...

Existing capacitive sensors have a pushbutton teach function ... Four new second-generation, single-channel, analog-to-IO-Link interface modules can convert a variety of analog input data, such as ...

capacitance-to-digital converter and bridge interface that is designed to be easily integrated with capacitive and bridge sensors. The chip features very fast measurement times, low operating power, ...

That’s what [Modest Maker] did and the resulting findings along with an attempt to beat the commercial system with some cheap capacitive sensors, are covered in a recent video that’s also ...
