It’s extremely tiny: it’s a little over a half-inch thick with a circumference the size of a US penny. The optical eye is magnetically coupled with the magnet side measuring only ¼” thick. It can be mounted to most clear, tinted, or painted surfaces up to ½” thick. The sensor operates in the daytime or complete darkness so it’s safe for use hidden inside your aquarium stand or in the back chambers of an all-in-one aquarium. The sensor is easy to place, easy to move, and easy to clean. The sensor connects with any HYDROS Sense Port using an aviation-style plug for safe operation. No additional power source is needed to run the sensor. Auto Top Off (ATO) Disclaimer Most Auto Top Off (ATO) systems have built-in "fail safe" mechanisms; however, caution MUST still be exercised. Your ATO reservoir must hold enough water to replenish evaporation but must not contain more than your system can handle to avoid flooding. We, nor the manufacturer, cannot be held responsible for any damages incurred.
