The Neptune Systems Optical Sensor plugs directly into the FMM allowing you to monitor the level of your sump, mixing station, or any other reservoir that has up to 1/4" thick walls. Using reflected infrared light, the sensor will signal your Apex when it changes state from being wet to dry or dry to wet. This sensor can be used for constructing your own ATO (auto top off), as a high-level warning sensor in your sump, water storage level sensor, and much more.
