DRAGINO - Sensor - LoRa - Water leakage sensor - WL03A-LB-EU868

The Dragino WL03A-LB is a LoRaWAN water leakage controller. The user can place the WL03A-LB + 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-LB indicates a water leak and sends an uplink to the IoT server via the LoRaWAN network. The WL03A-LB 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-LB supports BLE configuration and wireless OTA update, which make it easier for the user to use. WL03A-LB is powered by an 8500mAh Li-SOCI2 battery and is designed for long-term use of up to 5 years.

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