Dragino SW3L-LB LoRaWAN external flow sensor

SW3L-LB is it LoRaWAN flow sensor . It determines the volume of water flow and the uplink to the IoT server through the LoRaWAN network. User can use it for monitoring water consumption for buildings.

The SW3L-LB will send a volume of water every 20 minutes. He can too determine the state of the water flow and send an alarm , to avoid wasteful water use such as a broken toilet.

The SW3L-LB is designed for both indoor and outdoor use. It has a waterproof case and an industrial-grade battery for operation in low and high temperatures.

The LoRa wireless technology used in the SW3L-LB allows the device to send data and reach extremely long distances at low data rates. It provides ultra-long range spread-spectrum communication and high immunity to interference while minimizing current consumption.

SW3L-LB supports BLE configuration and wireless OTA update , which makes it easy for the user to use.

The SW3L-LB is powered by Li-SOCI2 battery with a capacity of 8500 mAh , designed for long-term use up to 5 years.

Each SW3L-LB is pre-loaded with a set of unique LoRaWAN registration keys, register these keys to your local LoRaWAN server and it will connect automatically after power on.
