## What is Senrium?

The Senrium app enables mobile devices to connect with a variety of sensor products, offering real-time monitoring of critical aquarium parameters that can swiftly change during emergencies. Currently, the Senrium offers the H1 Aquarium Monitor, which safeguards both you and your aquarium against equipment failures like malfunctioning heaters, chillers, pumps, filters, or leaks. Unlike expensive, cumbersome, and intricate aquarium controllers, Senrium simplifies the setup process: just place the sensor in your tank and define your limits. Senrium will promptly alert you when your aquarium requires attention.
