I. Introduction
Water leaks are a major concern for building complex managers, industrial plants, and businesses. In fact, “[the] leading cause of property losses in offices, apartments and other real estate facilities is from water damage” [1], and costs for water damage claims are approximately three times higher than other claims [1]. Consequently, there is a need for rapid and effective leak detection [1]. While various products exist to satisfy this demand, they all suffer various drawbacks. Many are quite costly, battery-powered devices periodically require batteries to be replaced, and mains-powered devices may be an added headache to wire when installing at large scale [2]–[4]. These issues lead to demand for innovation in the market.
