Description
The NB-WLD is an NB-IoT (NarrowBand IoT) water leak detection system, designed for critical infrastructure monitoring. It provides fast, real-time alerts for water leaks anywhere along the WLD sensing cable (up to 60m with prolong cables).
The device operates via NB-IoT connectivity, ensuring long-range and secure communication to SensDesk Technology-based portals (e.g., HWg-cloud.com). Users receive instant alerts via email or SMS when a leak is detected. The system also reports disconnected or damaged sensing cables, ensuring reliability.
NB-WLD is powered by an internal long-life battery (up to 3 years) or an external 5V power supply, making it ideal for unattended locations.
