### Basic details

The Dragino LWL02 works on the same LoRaWAN network as Conserv's Smart Collection Sensors (SCS). The rope leak cable can be laid on the ground to detect water leaks. When the rope detects water on the black surface under the yellow rope, the WL03A-LB will trigger a water leak event and send an uplink to IoT server via LoRaWAN network.
