Neptune Magnetic Optical Sensor
Optical Water Level Sensor for Neptune Apex Systems
The Neptune Magnetic Optical Sensor connects directly to your FMM module and uses reflected infrared light to detect changes in water level. When the sensor transitions from wet to dry or dry to wet, it instantly signals your Neptune Apex system, enabling precise monitoring and automated responses.
Accurate and Reliable Level Detection
Unlike mechanical float switches, the optical sensing technology provides reliable detection with no moving parts. The magnetic mounting design allows for secure and flexible placement within your aquarium system, sump, or water storage container.
Versatile Applications
The Neptune Magnetic Optical Sensor can be used in a wide range of aquarium automation tasks, including:
-
DIY ATO (auto top-off) systems
-
High-level warning sensors in sumps
-
Water storage level monitoring
-
Leak prevention and system alerts
-
Custom Apex-controlled automation projects
