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 ...

Electrical capacitance sensors detect and measure capacitance, which is the ability to store an electrical charge. Capacitive sensors are essentially oscillators, which open a capacitor that generates ...

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 ...
