The Dragino WL03A-LB is a rope-type, non-position LoRaWAN water leak sensor designed to detect water leakage over a laid leak-sensing cable. When water contacts the cable, the sensor immediately triggers a leak event and transmits alerts to an IoT server via LoRaWAN. It also records leak counts and duration for analysis.
