WL03A-NB -- NB-IoT None-Position Rope Type Water Leak Controller

The Dragino WL03A-NB is a NB-IoT None-Position Rope Type Water Leak Controller. User can lay the WL03A-NB + Water Leak Cable on the ground to detect water leakage. The water leak cable is sensitivity, when there is water over the leak cable. WL03A-NB will indicates a water leak event and uplink to IoT server via NB-IoT network.

The WL03A-NB 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.

WL03A-NB supports different uplink methods including MQTT, MQTTs, UDP & TCP for different application requirement, and support uplinks to various IoT Servers.

WL03A-NB supports BLE configure and OTA update which make user easy to use.

WL03A-NB is powered by 8500mAh Li-SOCI2 battery, it is designed for long-term use up to several years.

WL03A-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
