The Dragino LWL03A is a LoRaWAN None-Position Rope Type Water Leak Controller. Users can lay the LWL03A + Water Leak Cable on the ground to detect water leakage. The water leak cable is sensitive, when there is water over the leak cable. LWL03A will indicate a water leak event and uplink to the IoT server via the LoRaWAN network. An 8500mAh battery and target power LWL03A for a long time use up to 10 years.
The LWL03A 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. Each LWL03A is pre-loaded with a set of unique keys for LoRaWAN registration, register these keys to the LoRaWAN server and it will auto-connect after powering on.
