25		-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.
	21	+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.**
26	26
27		-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.
	23	+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.

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.
