Dragino LWL03A

The Dragino LWL03A is a LoRaWAN None-Position Rope Type Water Leak Controller. User can lay the water leak detector cable on the ground to detect water leakage. LWL03A will indicates a water leak event and send the information to the IoT server via LoRaWAN network.

Features Highlight

External water leak cable
Sensitive water leak cable
Water leak detection and counter
8500 mAh battery for long time use, up to 10 years.
Uplink on periodically and leakage event

IoT Server Integration

Users can conveniently access and monitor door status, open time, and open counts through the connected IoT server.

External Long Cable

The LWL03A 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.

Periodic Data Transmission

The XL270 communicates using Wi-Fi and LoRa, providing redundancy in communication protocols.

Pre-Loaded Unique Keys

LWL03A comes pre-loaded with unique keys for LoRaWAN registration, enabling automatic connection upon power-on, simplifying setup.

Battery-Powered

The LWL03A, powered by 8500 mAH Li-SoCl2 battery designed for long-term use, with a target lifespan of up to 10 years.

CASE STUDY

This case study explores the practical application of the Dragino LWL03A, highlighting its ability on detecting the water leak event.

Water Supply Monitoring:

By installing Dragino LWL03A at key points within water supply infrastructure, such as reservoirs, wells, or water storage facilities.

1. 1. 1. Real-time water leakage monitoring
      LWL03A equipped with a sensitive cable that can detect the water leak. When water is detected over the cable, the device indicates a water leak event.
    2. Water loss monitoring
      LWL03A has an ability to count the number of water leak event. From that data, you can make a calculation on how much water you lost.
