The Dragino WL03A-CB2 is a NB-IoT and LTE-M None-Position Rope Type Water Leak Controller. User can lay the 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-CB2 will indicates a water leak event and uplink to IoT server via NB-IoT/LTE-M network. The WL03A-CB 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.

You can use various IoT Servers and different uplink methods including MQTT, MQTTs, UDP and TCP.

The sensor node uses Quectel BG95-NGFF Multi-band LTE Cat M1/Cat NB2 module with GPS which can be used in most European countries. It has a card slot for an NB-IoT/LTE-M SIM card.

This device supports BLE for easy configuration and wireless OTA to update the firmware. WL03A-CB2 is powered by 19000mAh Li-SOCI2 battery. It is designed for many years of use.

WL03A-CB2 includes a one meter water leak cable. If you want to extend the lenght, you can order extra leak cable. (see below)
