Dragino WL03A Series | Cellular Rope Type Water Leak Sensor (NB-IoT) Offers Precision Engineering & ComplianceThe Dragino WL03A NB is an advanced water leak controller designed for high reliability environments such as data centers, warehouses, and industrial piping galleries. Unlike point source sensors, the WL03A utilizes a sensitive rope type leak cable that can be laid across large floor areas to detect moisture at any point along its length. Upon contact with water, the controller immediately triggers an uplink to the IoT server via NB IoT networks,
