The model 720 is a low-cost, compact capacitance vacuum gauge (CVG) based on the companyÕs variable capacitive sensor design. It produces a 0 to 5 Vdc or 0 to 10 Vdc output that is linear with ...

Well suited for precision ratiometric capacitive-sensor applications, the oscillator's output frequency is proportional to the ratio of C MEAS /C REF (C3/C4).

But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how capacitive soil moisture sensors work simply, clearly, and concisely.

Even with these limitations, capacitive touch sensors work well for many consumer applications. However, some situations involve more stringent requirements.

Capacitive sensors work by measuring a change in the properties of an electrode when a pathogen binds to it.

It is not straightforward to design the layout for capacitive sensors and still achieve a 5:1 SNR in the end system. This is further complicated when using an MBR device where developers don’t have ...
