This is a LoRaWAN sensor node from Dragino. The SW3L is a flow sensor that measures water flow between 2 and 100 L/min and communicates this value via the LoRa network. The sensor sends the value every 20 minutes. It can also detect water flow status and send an alarm to prevent water waste, such as a faulty toilet. An 8500 mAh Li-SOCI2 battery provides up to 10 years of battery life (details in the documentation). The sensor features G1/2" external threads on both sides. Each SW3L is preloaded with a set of unique LoRaWAN registration keys. These keys are registered on the LoRaWAN server and the connection is automatically established upon power-up.
