Apex optical sensor with magnet mount

Optical Level Sensor (OS-1)

This sensor conveniently plugs into your FMM and utilizes reflected infrared light to notify your Apex when the state changes from wet to dry or vice versa. It is a versatile tool that can be used to create your own ATO (auto-top-off) system, serve as a high-level warning sensor in your sump, monitor water storage levels, and much more.

The sensors can be easily mounted using custom brackets or inserted through a hole in a vessel. Each purchase includes a fastening nut and a silicone washer. Please note that these sensors are sold individually.
