Abstract: A fluid sensing system and approach having a leak sensor. The leak sensor may output a signal when a fluid is detected. The signal may go to an alarm circuit which can sound a warning or alert. The signal may also go to a control interface of a piece of equipment, such as a water heater, to shut off the piece equipment in an event that it is causing a leak of fluid. Also, the sensing system may have a low battery sensor and indicator in case a battery supplying power for the sensing system is running low. The sensing system may be made of analog circuitry and discrete components.

Abstract: A system having a fluid leak detector, an audio detection circuit, and a processor. The fluid leak detector may have an audio alarm. The audio detection circuit may have a sound sensor and an audio-to-electrical signal converter. The processor may have an electrical signal-to-status of fluid presence. The fluid leak detector, the audio detection circuit and the processor may use very little power when in a standby detection mode.
