4. Functionality
The NV-RA02C operates as a wireless contact sensor that detects the open or closed state of a magnetic reed switch. When the magnetic field changes—such as when a door or window opens or closes—the reed switch toggles its state. This change is detected by the internal microcontroller, which then transmits a LoRaWAN uplink message containing the new state information.
The device periodically sends status updates or event-driven messages to a LoRaWAN gateway, which forwards the data to a network server or cloud platform. The server can then trigger alerts, log events, or integrate the data into building management systems (BMS), industrial control systems (ICS), or IoT dashboards.
Use Cases and Applications:
- Smart Building Automation: Monitor door/window status for security and energy management.
- Industrial Equipment Monitoring: Detect access to control panels, cabinets, or machinery enclosures.
- Utility Infrastructure: Monitor valve or gate positions in water, gas, or power systems.
