Smart leak detection and water level monitoring
Protect your property from costly water damage with a reliable IoT-based leak detection system. Our sensors detect everything from small leaks under sinks to larger flooding risks in basements, garages, and technical rooms. Monitor all areas remotely through one platform and act immediately when a problem is detected.
How IoT prevents water damage in buildings
Even a small leak can cause serious damage if it goes unnoticed. IoT sensors for water monitoring provide early warnings, helping property owners and facility managers prevent downtime and expensive repairs.

Detect Local Leaks Under Sinks or in Service Rooms
Compact leak sensors detect the first signs of moisture under kitchen units, dishwashers, or service rooms. Instant alerts are sent to your system so maintenance staff can respond before the leak spreads.

Detect leaks along cooling lines or in IT-Rooms
Cable-based leak sensors detect water along entire lengths of pipes or floors in sensitive areas such as IT rooms, server spaces, or HVAC systems. This helps protect equipment and prevent system interruptions.

Flood alarm in garages and basements
Ultrasonic and ToF level sensors monitor water buildup in low-lying areas such as basements, garages, and technical rooms. Real-time alerts help prevent costly flooding and damage to infrastructure.
