4. Functionality
The NV-R718DB2 functions as a wireless analog signal acquisition node within a LoRaWAN network. It continuously monitors two analog voltage inputs (0–10V range) and converts them into digital values using its internal ADC. These readings are then transmitted periodically or upon threshold events to a LoRaWAN gateway, which forwards the data to a network server or cloud platform for processing and visualization.
The integrated dual spring-type vibration sensors detect mechanical vibrations or shocks, enabling the device to serve as both an analog data logger and a vibration monitoring unit. This dual functionality makes it suitable for industrial equipment monitoring, structural health diagnostics, HVAC system supervision, and environmental sensing.
Typical Use Cases:
- Monitoring analog output from pressure, temperature, or humidity transmitters (0–10V type).
- Detecting vibration or movement in motors, pumps, or rotating machinery.
- Supervising building or bridge vibration for structural integrity.
- Integrating with industrial control systems for predictive maintenance.
- Remote monitoring of analog signals in agriculture, utilities, or smart city applications.
Compatibility:
- Works with any LoRaWAN-compliant gateway and network server (e.g., The Things Network, ChirpStack, Loriot).
- Data can be integrated into IoT platforms via MQTT, HTTP, or API interfaces.
- Supports over-the-air configuration and firmware updates (depending on network setup).
