US Patent 11946830 System and method for wireless water leak detection

The system and method for wireless water leak detection provides for manual prevention of external action, such as an external alarm and/or valve shut-off, if a leak sensor can be reached by a respondent within a pre-set time threshold. Upon detection of a leak by a leak sensor, a local alarm, such as an audible alarm or the like, is initiated. Additionally, at the time of detection, a first time is recorded. A first alarm signal is transmitted from the leak sensor to a base station. The first alarm signal includes data representative of the recorded first time. If manual input is not received by the leak sensor within a pre-set time threshold measured from the first time, then the base station transmits a second alarm signal to at least one external device, and may further wirelessly transmit a shut-off signal to a valve controller for closing an associated valve.
