The Leak Detection Sensor is a solid-surface leak detector manufactured by AutoAqua (Taiwan) that senses freshwater or saltwater pooling underneath it and triggers protective actions and alerts. It plugs into any HYDROS Sense Port with its GX12 aviation-style connector and requires no separate power source. Configure it through the app to flash a warning color, shut off a pump or skimmer, and send a mobile notification the moment a leak is detected.
