Abstract
A method, apparatus, and system to detect a self-capacitance activation in view of a self-capacitance measurement of a first electrode. The method, apparatus, and system further to detect a mutual capacitance activation in view of a mutual capacitance measurement of a pair of electrodes, and to determine the presence of water proximate to the capacitive button when the self-capacitance activation is false and the mutual capacitance activation is true. The capacitive button is disposed on a substrate.
