SW3L DN15 LoRaWAN Flow Sensor 868MHz

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