1.1	20
39.6	21
67.3	22	The Dragino SW3L-LB is a (% style="color:blue" %)LoRaWAN Flow Sensor(%%). It detects water flow volume and uplink to IoT server via LoRaWAN network. User can use this to(% style="color:blue" %) monitor the water usage for buildings.
1.1	23
67.3	24	The SW3L-LB will send water flow volume every 20 minutes. It can also (% style="color:blue" %)detect the water flow status(%%) and (% style="color:blue" %)send Alarm(%%), to avoid the waste for water usage such as broken toilet case.
1.1	25
67.3	26	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.
1.1	27
67.3	28	The LoRa wireless technology used in SW3L-LB allows 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.
1.1	29
67.3	30	SW3L-LB (% style="color:blue" %)supports BLE configure(%%) and (% style="color:blue" %)wireless OTA update(%%) which make user easy to use.
62.4	31
67.3	32	SW3L-LB is powered by (% style="color:blue" %)8500mAh Li-SOCI2 battery(%%), it is designed for long term use up to 5 years.
1.1	33
67.3	34	Each SW3L-LB is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and press the button to activate the SW3L-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
