Dragino WL03A Water Leak Sensor (LoRaWAN, NB-IoT & LTE-M)

 

The Dragino WL03A Water Leak Sensor is designed for reliable detection of water leaks and flooding events across LoRaWAN, NB-IoT, and LTE-M networks. It provides early warning of unwanted water ingress in environments where leaks can cause operational disruption, equipment damage, or safety risks.

Multi-Network Connectivity The WL03A platform is available in variants that support LoRaWAN, NB-IoT, and LTE-M, allowing deployment on private LoRaWAN networks or carrier-managed cellular networks. This flexibility supports a wide range of installations, from single buildings through to distributed infrastructure.

Designed for Leak and Flood Detection Using an external water leak probe, the WL03A detects the presence of water at floor level or within containment areas. It is well suited to plant rooms, server rooms, basements, pump stations, and other areas where early detection is critical.

Flexible Power Options Battery-powered and solar-powered variants are available across the WL03A range, supporting long-term, low-maintenance operation in both indoor and outdoor environments.

Enhanced Functionality with Telemetry2U Integration While the WL03A can be connected to compatible third-party platforms, Telemetry2U is the recommended option for customers seeking a supported, end-to-end monitoring solution. Integration with the Telemetry2U IoT platform enables dashboards, alerts, historical event logging, and device management from a single interface.
