WL03A-LB is it positionless LoRaWAN water leak controller . The user can put WL03A-LB + earth leakage cableto detect a water leak. The water leakage cable is sensitive when water is over the leakage cable. WL03A-LB indicates water leakage event and connects to the IoT server via the LoRaWAN network.
The WL03A-LB will periodically send data every 2 hours and for every water leak. It also calculates the time of the water leak and calculates the duration of the last water leak.
WL03A-LB supports BLE configuration and wireless OTA update , which makes it easy for the user to use.
WL03A-LB is powered by Li-SOCI2 battery with a capacity of 8500 mAh , designed for long-term use up to 5 years.
Each WL03A-LB comes pre-loaded with a set of unique LoRaWAN registration keys, register these keys to your local LoRaWAN server and it will connect automatically after power on.
