--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.**
++The Dragino DDS20-LB is a (% style="color:blue" %)**LoRaWAN Ultrasonic liquid level sensor**(%%) for Internet of Things solution. It uses (% style="color:blue" %)**none-contact method **(%%)to measure the (% style="color:blue" %)**height of liquid**(%%) in a container without opening the container, and send the value via LoRaWAN network to IoT Server.
--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.
++The DDS20-LB sensor is installed directly below the container to detect the height of the liquid level. User doesn't need to open a hole on the container to be tested. The none-contact measurement makes the measurement safety, easier and possible for some strict situation.
--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.
++DDS20-LB uses (% style="color:blue" %)**ultrasonic sensing technology**(%%) for distance measurement. DDS20-LB is of high accuracy to measure various liquid such as: (% style="color:blue" %)**toxic substances**(%%), (% style="color:blue" %)**strong acids**(%%), (% style="color:blue" %)**strong alkalis**(%%) and (% style="color:blue" %)**various pure liquids**(%%) in high-temperature and high-pressure airtight containers.
--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.

--(% style="color:blue" %)**Step 2:**(%%) Activate on SW3L-LB
++== 2.1 How it works ==
--Press the button for 5 seconds to activate the SW3L-LB.
++The DDS20-LB is configured as (% style="color:#037691" %)**LoRaWAN OTAA Class A**(%%) mode by default. It has OTAA keys to join LoRaWAN network. 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 DDS20-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
--(% style="color:green" %)**Green led**(%%) will fast blink 5 times, device will enter (% style="color:blue" %)**OTA mode**(%%) for 3 seconds. And then start to JOIN LoRaWAN network. (% style="color:green" %)**Green led**(%%) will solidly turn on for 5 seconds after joined in network.
++(% style="display:none" %) (%%)
--After join success, it will start to upload messages to TTN and you can see the messages in the panel.
++== 2.2 Quick guide to connect to LoRaWAN server (OTAA) ==
--== 2.3 Uplink Payload ==
++Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]]  as a LoRaWAN gateway in this example.
--=== 2.3.1 Device Status, FPORT~=5 ===
++The LPS8v2 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.

--Include device configure status. Once SW3L-LB Joined the network, it will uplink this message to the server. After that, SW3L-LB will uplink Device Status every 12 hours.
--Users can use the downlink command(**0x26 01**) to ask SW3L-LB to send device configure detail, include device configure status. SW3L-LB will uplink a payload via FPort=5 to server.
