4. Functionality
The NV-R206A operates as a wireless water leak detection node within a LoRaWAN network. It continuously monitors its connected sensing cable or probe for the presence of water or conductive liquids. When a leak is detected, the device triggers an internal event that generates a LoRa uplink message containing the alarm status, timestamp, and device ID.
This message is transmitted to a LoRa gateway, which forwards it to a network server or cloud platform for processing, visualization, and alerting. Depending on configuration, the NV-R206A can also send periodic status updates, battery level reports, and environmental diagnostics.
Use Cases and Applications:
- Building Management Systems (BMS): Early detection of water leaks in mechanical rooms, basements, or HVAC systems.
- Data Centers: Monitoring under raised floors or near cooling systems to prevent equipment damage.
