The invention is related to capacitive sensing and detection systems and methods. In one embodiment, a capacitive sensor system comprises a first electrode arrangement having a first characteristic and related to a first capacitance, a second electrode arrangement having a second characteristic different from the first characteristic and related to a second capacitance, and a control unit coupled to the first and second electrode arrangements and configured to identify an object-dependent variable from at least one of the first and second characteristics and first and second capacitances.
