SW3L-LB-004 LoRaWAN Flow Sensor

The SW3L-LB is a LoRaWAN-based flow sensor designed to accurately monitor water flow volume and detect abnormal flow conditions in smart water management systems. It periodically transmits flow data to an IoT server and can send instant alarms to prevent water wastage, such as in cases of leaks or broken fixtures.

Built for indoor and outdoor applications, the SW3L-LB features a weatherproof enclosure and an industrial-grade 8500mAh Li-SOCl₂ battery that provides up to 5 years of operation. It supports BLE configuration, wireless OTA updates, and Datalog functionality for data backup when no LoRaWAN network is available.
