Dragino SW3L LoRaWAN external flow sensor

SW3L is a LoRaWAN flow sensor. It determines the volume of water flow and the uplink to the IoT server through the LoRaWAN network. The user can use this to monitor water consumption for buildings.

The SW3L is powered by an 8500mAh Li-SOCI2 battery, rated for up to 10 years of continuous use. (Actually battery life depends on usage environment and update period.)

The SW3L will send a volume of water every 20 minutes. It can also detect the state of water flow and send an alarm to avoid waste water use, such as a broken toilet bowl.

The SW3L 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.

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