The Dragino SW3L-LB is a LoRaWAN Flow Sensor. It detects water flow volume and uplinks to the IoT server via the LoRaWAN network. Users can use this to monitor the water usage for buildings.
The SW3L-LB will send water flow volume every 20 minutes. It can also detect the water flow status and send an Alarm, to avoid waste from water usage such as a broken toilet case.
SW3L-LB is designed for both indoor and outdoor use. It has a weatherproof enclosure and industrial-level battery to work in low to high temperatures.
The LoRa wireless technology used in SW3L-LB allows the device to send data and reach extremely long ranges at low data rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
SW3L-LB supports BLE configuration and wireless OTA update which makes users easy to use.
An 8500mAh Li-SOCI2 battery powers SW3L-LB, designed for long-term use for up to 5 years.
Each SW3L-LB is pre-loaded with a set of unique keys for LoRaWAN registrations, register these keys to the local LoRaWAN server and it will auto-connect after power on.
