News facts: New AS8579 capacitive sensor uses novel technique for fool-proof, hands-on detection design Enables sensing placement within the steering-wheel industry’s first completely reliable ...

Murata has developed newly capacitive type MEMS pressure (barometer) sensor (2.3 x 2.6 mm typ.).

Likely the first is the bigger problem for a capacitive sensor. I see matching to about 20% between the tipping bucket and an old style calibrated cylinder, manual check daily, rain gauge.

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 … ...
