DRAGINO water leak sensor

Overview

Dragino LWL03A is a rope type, location-independent LoRaWAN water leakage controller. User can place the LWL03A and water leakage cable on the ground to detect water leakage. The water leakage cable is sensitive, when there is water above the leakage cable, the LWL03A will indicate a water leakage event and send an uplink to the IoT server via the LoRaWAN network.

The LWL03A is powered by an 8500mAh battery and is designed for long-term use of up to 10 years.

The LWL03A sends data regularly every 2 hours and whenever a water leak occurs. It also counts the water leak times and calculates the duration of the last water leak.

Each LWL03A is preloaded with a set of unique keys for LoRaWAN registration, which are registered on the LoRaWAN server and automatically connect after power on.
