4. Functionality
The NV-R311K operates as a wireless vibration and tilt monitoring node within a LoRaWAN® network. It continuously monitors vibration levels and tilt angles using an integrated MEMS accelerometer. When vibration or motion is detected, the device increments an internal counter and can transmit event data to a LoRa gateway.
Operating Principle:
- The sensor detects vibration or tilt events through its accelerometer.
- Each event is processed and counted internally.
- Data packets containing event counts, tilt status, and timestamp information are transmitted periodically or upon threshold exceedance.
- The LoRaWAN® network forwards the data to a network server or cloud platform for visualization, analysis, or integration with SCADA/IoT systems.
Use Cases and Applications:
- Industrial Equipment Monitoring: Detects abnormal vibration patterns in motors, pumps, or compressors.
- Structural Health Monitoring: Monitors tilt or vibration in bridges, towers, or buildings.
- Smart City Infrastructure: Tracks vibration activity in public installations or transportation systems.
- Asset Tracking and Security: Detects unauthorized movement or tampering of stationary assets.
- Agricultural and Environmental Monitoring: Monitors vibration or tilt in remote installations such as irrigation systems or weather stations.
- Predictive Maintenance: Provides early warning of mechanical imbalance or misalignment.
