The NV-R311B operates as a wireless open/close detection sensor using a Hall effect sensor to detect the presence or absence of a magnetic field. When a magnet (typically mounted on a door or window) moves away from or toward the sensor, the Hall element detects the change and triggers a state update (open or closed). This state is then transmitted via the LoRaWAN network to a central gateway or network server.
Use Cases and Applications:
- Smart Buildings: Monitor door and window status for security and energy management.
- Industrial Facilities: Track cabinet or equipment enclosure access.
- Warehouses: Detect loading dock or gate openings.
