Capacitive proximity sensors use the face or surface of the sensor as one plate of a capacitor, and the surface of a conductive or dielectric target object as the other. The capacitance varies ...
Capacitive linear position sensors measure position, displacement, vibration, and run out (thickness), primarily in a noncontact manner. They have good accuracy and very high resolution, but may be ...
Happily there is a solution in the form of capacitive sensor probes, and it is these that [Electrobob] is incorporating in to a home automation system. Unfortunately the commercial capacitive ...
