4. Functionality
The NV-R718AD operates as a wireless water leak detection and temperature monitoring node within a LoRaWAN® network. The device continuously monitors the connected leak detection cable for changes in electrical resistance caused by water contact. When water is detected, the sensor immediately transmits an alarm message via LoRaWAN® to the network server, which can then trigger alerts, notifications, or automated responses in a building management system (BMS) or IoT platform.
The integrated temperature sensor provides periodic environmental readings, allowing users to monitor ambient conditions in addition to leak status. This dual-function design supports applications such as data center monitoring, HVAC system supervision, pipeline leak detection, and facility maintenance.
The device communicates wirelessly with a LoRaWAN® gateway, which forwards data to a network server and application platform. Configuration parameters such as reporting intervals, alarm thresholds, and transmission power can be adjusted remotely via downlink commands.
Typical Use Cases:
- Water leak detection in server rooms, data centers, and communication facilities
- Monitoring of HVAC systems, chilled water lines, and condensate drains
- Leak detection in storage areas, basements, and mechanical rooms
