Abstract
A method for capacitive sensing is provided. The method comprises: obtaining, by a processing system and using a first set of electrodes from a plurality of electrodes of an input device, first resulting signals based on driving a second set of electrodes from the plurality of electrodes, wherein the first set of electrodes and the second set of electrodes are oriented on a same axis of orientation; obtaining, by the processing system, second resulting signals based on operating a third set of electrodes from the plurality of electrodes in an absolute capacitance sensing (ABS) scheme; and determining, by the processing system, a presence of moisture on a sensing region of the input device based on the first resulting signals and the second resulting signals.
