SW3L-LS-010 LoRaWAN Flow Sensor

The SW3L-LS is a solar-powered LoRaWAN flow sensor designed to monitor water flow volume and usage patterns in smart water management systems. It transmits flow data every 20 minutes and can detect abnormal flow conditions to send instant alarms, preventing water waste from leaks or faulty fixtures.

Built for indoor and outdoor applications, the SW3L-LS features a weatherproof enclosure and is powered by a solar panel with a 3000mAh Li-ion battery, enabling long-term, maintenance-free operation of up to 5 years. It supports BLE configuration, wireless OTA firmware updates, and a Datalog feature for offline data storage.
