Dragino WL03A Series | Cellular Rope Type Water Leak Sensor (NB-IoT)

The Dragino WL03A-NB is an advanced water leak controller designed for high-reliability environments such as data centers, warehouses, and industrial piping galleries. Unlike point-source sensors, the WL03A utilizes a sensitive rope-type leak cable that can be laid across large floor areas to detect moisture at any point along its length. Upon contact with water, the controller immediately triggers an uplink to the IoT server via NB-IoT networks, providing real-time alerts. It also calculates the duration of each leak event and maintains a count of occurrences, ensuring facility managers have a complete history of site safety.

Reliable Flood Mitigation

Instant Alarm Uplink In addition to periodic heartbeats every 2 hours, the device sends an immediate uplink the moment a leak is detected for rapid response. Remote Configuration Fully manageable via Bluetooth (BLE) for local setup or through downlink commands and wireless OTA updates for remote maintenance.

Professional Safety Scenarios

• Data Centers (IDC): Monitor under-floor AC units and water-cooled server racks for condensation or pipe leaks. • Smart Buildings: Deploy in elevator shafts, basements, and utility rooms to prevent structural water damage. • Industrial Piping: Wrap around critical joints and valves to identify leaks before they lead to system failure.

Dragino Power Options

• Model NB: 8500mAh Non-rechargeable battery for long-term monitoring. • Model NB2: High-capacity 19000mAh battery for maximum deployment life. • Model NS: 3000mAh Solar-powered rechargeable battery for maintenance-free use.
