The Dragino WL03A-LB is a LoRaWAN None-Position Rope Type Water Leak Controller. User can lay the WL03A-LB + Water Leak Cable on the ground to detect water leakage. The water leak cable is sensitivity, when there is water over the leak cable. WL03A-LB will indicates a water leak event and uplink to IoT server via LoRaWAN network.

The WL03A-LB will send periodically data every 2 hours as well as for each water leak event. It also counts the water leak times and calculate last water leak duration.

WL03A-LB supports BLE configure and wireless OTA update which make user easy to use.

WL03A-LB is powered by 8500mAh Li-SOCI2 battery, it is designed for long term use up to 5 years.

Each WL03A-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.
