The Dragino WL03A-LB is a LoRaWAN None-Position Rope Type Water Leak Controller. Users can lay the WL03A-LB + Water Leak Cable on the ground to detect water leakage. The water leak cable is sensitive, when there is water over the leak cable. WL03A-LB will indicate a water leak event and uplink to the IoT server via the LoRaWAN network.
The WL03A-LB will send periodic data every 2 hours for each water leak event. It also counts the water leak times and calculates the last water leak duration.
WL03A-LB supports BLE configure and wireless OTA update, making users easy to use.
WL03A-LB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to 5 years.
Each WL03A-LB is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto-connect after power on.

DR-WLN-XX Water Leak Cable Sensor:
DR-WLN detection cable is made of two light high-density polyethylene (HDPE) wires around the spiral axis. Compared with the parallel structure of the detection line, the spiral structure can reduce the environmental electromagnetic interference and false alarm rate, and greatly improve the strength and service life of the cable.
With a unique manufacturing process, the cable is fast and dry, enabling the detection host to be quickly and accurately reset and easy to use. The cable is made of anti-corrosion, halogen-free, non-toxic materials, meeting environmental standards.
