Abstract
Various embodiments of the present technology may provide methods and apparatus for a capacitive sensor configured to detect rain. The capacitive sensor may provide a reception electrode in communication with a drive electrode to form an electric field and a ground electrode surrounding the reception and drive electrodes. The ground electrode may couple the rain to a ground potential resulting in a decrease in the capacitance of the capacitive sensor.
