Abstract
A water-resistant capacitance sensing apparatus comprising a plurality of capacitive sense elements and a capacitance sensing circuit configured to measure both the mutual capacitance and self-capacitance on the plurality of capacitive sense elements. A method for water-resistant capacitance sensing, the method comprising performing a self-capacitance scan and a mutual capacitance scan, and detecting, by a processing device, a presence of an object with the plurality of sense elements. The method further determines whether the detected presence of the object is legitimate.
