The Dragino WL03A-NB is a NB-IoT None-Position Rope Type Water Leak Controller. Users can lay the WL03A-NB + 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-NB will indicate a water leak event and uplink to the IOT server via the NB-IoT network.
The WL03A-NB 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-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirements, and supports uplinks to various IoT Servers.
WL03A-NB supports BLE configure and OTA update which make users easy to use.
WL03A-NB is powered by an 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.
WL03A-NB has an optional built-in SIM card and default IoT server connection version. Which makes it work with a simple configuration.

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.
