DRAGINO NB-IoT & LoRaWAN Power Outage Monitoring Sensor
DRAGINO NB-IoT & LoRaWAN Power Outage Monitoring Sensor is a power monitoring sensor designed to remotely detect AC power outages and low-voltage conditions. It monitors the status of an AC supply and sends event notifications and periodic status data over a network. The device supports BLE configuration, wireless firmware updates and local data logging when network communication is unavailable. With support for 85-305 VAC supply and an internal rechargeable backup battery, it is suited to distributed power monitoring applications.
The DRAGINO NB-IoT & LoRaWAN Power Outage Monitoring Sensor is a LoRaWAN-based power outage monitoring sensor for applications where the status of an AC power supply needs to be monitored remotely.
The sensor uses optocoupler isolation to detect the presence and condition of an AC supply. It provides power outage monitoring when the detected voltage falls below the manufacturer's specified outage threshold and low-voltage monitoring for abnormal supply conditions. When a monitored state changes, the DRAGINO LoRaWAN Power Outage Monitoring Sensor can send an event packet through the LoRaWAN network.
The device operates as a LoRaWAN 1.0.3 Class A end node and supports multiple regional frequency bands, including AU915 and AS923. It can be configured using Bluetooth, while LoRaWAN downlink commands can also be used for remote configuration. Wireless OTA firmware updates are supported for firmware maintenance and regional configuration.
How it works
- The DRAGINO LoRaWAN Power Outage Monitoring Sensor monitors an AC power supply through an isolated detection circuit.
- A power outage is detected when the monitored voltage falls below the specified outage threshold of 17 V.
- Low-voltage monitoring is specified for conditions below 180 V.
- A change in power or low-voltage status triggers an uplink event.
- The sensor also sends periodic status data to the server.
- An internal rechargeable battery allows the device to continue monitoring during a power interruption.
- If the LoRaWAN network is unavailable, the datalog function can retain sensor records for later transmission after communication is restored.
Why choose this product?
- Remote power failure monitoring - Receive power status information through an existing LoRaWAN infrastructure.
- Event-based reporting - Changes in power and low-voltage status can generate an immediate data transmission.
- Local data logging - Sensor records can be retained when the LoRaWAN connection is temporarily unavailable.
- Low-power operation - The manufacturer specifies a sleep-mode consumption of 50 µA at 3.3 V.
- Flexible configuration - Parameters can be configured through BLE, UART or LoRaWAN downlink commands.
- Long-range wireless communication - LoRaWAN provides a practical communications method for distributed monitoring installations.
- Remote firmware management - OTA firmware updating is supported.
Benefits
The DRAGINO LoRaWAN Power Outage Monitoring Sensor is useful where power supply status needs to be monitored across multiple distributed locations without requiring a dedicated communications connection at every monitoring point.
Its event reporting can help identify power interruptions and abnormal voltage conditions promptly, while the datalog function provides a way to recover records following temporary LoRaWAN communication failures.
The combination of AC power monitoring, NB-IoT & LoRaWAN connectivity and backup battery operation makes the DRAGINO LoRaWAN Power Outage Monitoring Sensor suitable for unattended monitoring points where reliable status information is important.
