In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how ...

Ever wondered how a touch-sensitive screen works? The answer is capacitive sensing, which can detect the presence of your finger through the protective glass sheet and doesn't require any pressure.

Capacitive sensors work by using the human body as one of the capacitive plates of an electrical circuit. A leader in low power capacitance touch sensors, NXP offers a range of auto calibrating ...

Like most (if not all) Hackaday readers, I like to know how the technology I use works. I’m always amazed, for example, how many otherwise smart people have no idea how the cellphone network works ...

AMS has announced a configurable capacitive sensing front end which allows speed and resolution to be traded to optimise designs. Called PCap04, it can capture and digitise 50,000 times per second at ...

Google is reportedly developing a technology that will automatically summon its AI assistant, Gemini, when the phone is ...
