DRAGINO Water flow meter G3/4'' / DN20 with solar panel

Overview

The Dragino SW3L-LS is a LoRaWAN flow sensor. It detects the water flow rate and establishes a connection to the IoT server via the LoRaWAN network. The user can use it to monitor water consumption in buildings.

The SW3L-LS sends the water flow rate every 20 minutes. It can also detect the water flow status and send an alarm to prevent water wastage, such as a broken toilet cistern. SW3L-LS is suitable for both indoor and outdoor use. It has a weatherproof housing and an industrial-grade battery for use in low to high temperatures.

The LoRa radio technology used in the SW3L-LS enables the device to transmit data and achieve extremely long ranges at low data rates. It offers spread spectrum communication with extremely long range and high noise immunity with minimal power consumption.

SW3L-LS supports BLE configuration and wireless OTA updates, making it easier for the user to use.

SW3L-LS is powered by a solar cell + Li-on battery and is designed for long-term use of up to 5 years.

Each SW3L-LS is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will connect automatically after switching on.
