The higher the dithering factor, the more sensitive the proximity sensing is. However, the speed

will be slower.

Controls the number of dithered impedance sampling between successive calibrations. Shorter

calibration interval allows it to adapts quickly to changes in environmental factors, but reduces

the sensitivity to slowly approaching hand.
