Hydros Water Level Sensor The Hydros Water Level Sensor is an optical HYDROS Sense Port accessory for monitoring aquarium, sump, reservoir, or dosing-container water level. It helps users track high or low water conditions without moving float parts, making it useful for ATO safety, dosing-container refill alerts, sump level protection, reservoir monitoring, and general freshwater or saltwater aquarium automation. HYDROS Water Level Sensor Overview This compact optical sensor plugs into an available HYDROS Sense Port and is powered directly through the controller, so no separate power supply is required. It can be used as a high-level or low-level sensor depending on the setup, and the magnetic mount allows it to be positioned in aquariums, sumps, all-in-one back chambers, overflow areas, ATO reservoirs, and dosing containers. In the HYDROS app, the sensor can be used for alerts or to support equipment actions when paired with compatible HYDROS-controlled outlets. Optical Water Level Monitoring Features Optically senses aquarium or container water level without a moving float arm. Can be configured for high-level or low-level monitoring applications. Useful for ATO control, sump level alerts, dosing-container refill reminders, reservoir monitoring, and dry-run protection. Magnetic mounting makes placement simple and allows the sensor to be moved for cleaning or repositioning. Connects directly to a HYDROS Sense Port using a secure GX12 aviation-style connector. No additional power supply is required when connected to a compatible HYDROS Control device. Suitable for freshwater and saltwater aquarium systems. Hydros Water Level Sensor Specifications Product type: HYDROS optical water level sensor UPC: 4714041211955 Connection: HYDROS Sense Port Sensor thickness: 0.55 in Magnet mount thickness: 0.25 in Sensor diameter: 0.75 in Cord length: 98 in Mounting style: Magnetic attachment Application: Freshwater and saltwater water-level monitoring Water Level Sensor Compatibility Notes The Hydros Water Level Sensor requires a compatible HYDROS Control device with an available Sense Port. Equipment control actions, such as shutting off a pump or controlling ATO equipment, require the connected equipment to be on a compatible HYDROS-controlled outlet or output. Confirm the wet and dry sensor states in the HYDROS app before relying on the sensor for automation. Official HYDROS Water Level Sensor Video Setting Up the HYDROS Water Level Sensor Mount the sensor at the desired water level, connect it to an available green HYDROS Sense Port, and add the input in the HYDROS app. Test the sensor by changing the water level or moving the sensor through wet and dry states, then configure the alerts, ATO rules, dosing-container reminders, or equipment responses needed for the application.
