US Patent 10393687 Multi-directional water sensor

A multi-directional water sensor comprises a housing having multiple conductive pads on the outer surface of the housing at locations spaced around the periphery of the housing, an electrical power source coupled to the conductive pads, and multiple electrical conductors located inside the housing and connecting multiple pairs of the contacts so that electrical current can flow between different pairs of the contacts when they are connected by water. The housing may have a generally rectangular shape, with the contacts located at the corners of the housing. The multiple electrical conductors are connected to an alarm that is energized when electrical current flows between any pair of the contacts.
