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.
25 +The Dragino (% style="color:blue" %)**DS20L is a smart distance detector**(%%) base on long-range wireless LoRaWAN technology. It uses (% style="color:blue" %)**LiDAR sensor**(%%) to detect the distance between DS20L and object, then DS20L will send the distance data to the IoT Platform via LoRaWAN.
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. 
27 +DS20L allows users to send data and reach extremely long ranges via LoRaWAN. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current 
28 +consumption. It targets professional wireless sensor network applications such smart cities, building automation, and so on.
28 28  
29 -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.
30 +DS20L has a (% style="color:blue" %)**built-in 2400mAh non-chargeable battery**(%%) for long-term use up to several years*. Users can also power DS20L with an external power source for (% style="color:blue" %)**continuous measuring and distance alarm / counting purposes.**
30 30  
31 -The LoRa wireless technology used in DDS20-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.
32 +DS20L is fully compatible with (% style="color:blue" %)**LoRaWAN v1.0.3 Class A protocol**(%%), it can work with a standard LoRaWAN gateway.
32 32  
33 -DDS20-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
34 +DS20L supports (% style="color:blue" %)**Datalog feature**(%%). It will record the data when there is no network coverage and users can retrieve the sensor value later to ensure no miss for every sensor reading.
34 34  
35 -DDS20-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
