摘要: A sensor apparatus includes a unit, calculation switch circuit and control unit. The unit has plurality of detection electrodes each having capacitance changed by proximity target object. calculates first distance, which is distance between the object capable switching state in signal voltage for detecting supplied second an electrically floating state, selects at least two one switched from to state. controls cause correspond distance.
