4. Functionality
The NV-R313W operates as a wireless water leak detection node within a LoRaWAN network. The rope sensor continuously monitors for the presence of water along its length. When water contacts the rope, the sensor’s conductive elements detect the change in resistance, triggering an internal signal. The device then transmits an alarm message via LoRaWAN to the network server.
Once the rope dries and the leak condition clears, the device sends a recovery message indicating normal status. Periodic status reports (heartbeat messages) can also be configured to confirm device health and connectivity.
Use Cases and Applications:
- Data Centers: Detect leaks under raised floors or near cooling systems.
- Commercial Buildings: Monitor basements, mechanical rooms, and HVAC condensate lines.
- Industrial Facilities: Protect equipment rooms, pump stations, and process areas.
- Residential Buildings: Detect leaks near water heaters, washing machines, or plumbing fixtures.
- Infrastructure Monitoring: Integrate into smart city or facility management systems for predictive maintenance.
