Capacitive Sensing Introduction
What is capacitive Sensing
A moving conductive object represents a moving electrode.
The interaction with a static electrical field results in a change of
capacitance.
The capacitive sensor detects this change of capacitance.
Can be used to create touch switches, touch screens, touch pads and
proximity sensors
