DRAGINO · Sensor · LoRa · None-Position Rope Type Water Leak Controller with Solar · WL03A-LS-EU868

The Dragino WL03A-LS is a LoRaWAN water leakage controller. The user can place the WL03A-LS + water leakage cable on the ground to detect water leaks. The water leakage cable is sensitive when there is water above the leakage cable. WL03A-LS indicates a water leak and sends an uplink to the IoT server via the LoRaWAN network. The WL03A-LS sends data regularly every 2 hours and for each water leak event. It also counts the water leak times and calculates the duration of the last water leak.

The WL03A-LS supports BLE configuration and wireless OTA updating, making it easier for the user to use.

The WL03A-LS is powered by a solar-powered + Li-on battery and is designed for long-term use of up to 5 years.

Each WL03A-LS is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will connect automatically after switching on.
