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.

The Dragino LWL02 is a LoRaWAN Water Sensor. When there is water between the two metal probes, LWL02 indicates a water leak event and uplink to IoT server via LoRaWAN network.

LWL02 is powered by 2 x AAA batteries and target for long time use, these two batteries can provide about 16,000 ~ 70,000 uplink packets, which result in 2 ~ 10 years battery life. After battery running out, user can easily open the enclosure and replace with 2 common AAA batteries.

The LWL02 will send periodically data every day as well as for each water leak event. It also counts the water leak times and calculate last water leak duration. User can also disable the uplink for each water leak event, instead, device can count each event and uplink periodically.

Each LWL02 is pre-load with a set of unique keys for LoRaWAN registration, register these keys to LoRaWAN server and it will auto connect after power on.
