Abstract
A water sensor comprises a housing including a top portion and a bottom portion; a controller positioned within the housing; a power source electrically coupled to the controller to energize the controller; and a continuity sensor electrically coupled to the controller and including an inner arcuate portion and an outer arcuate portion, the inner arcuate portion having an electrically conductive surface spanning at least 300 degrees, the outer arcuate portion having an electrically conductive surface spanning at least 300 degrees and substantially surrounding the inner arcuate portion to define an gap therebetween, wherein the water sensor is structured to transition from a first logical state to a second logical state responsive to water bridging the gap, and wherein the controller is structured to transmit a wireless water detection signal responsive to the water sensor transitioning to the second logical state.
