20 -The Dragino DDS45-LB is a (% style="color:blue" %)** LoRaWAN Distance Detection Sensor**(%%) for Internet of Things solution. It is used to measure the distance between the sensor and a flat object. The distance detection sensor is a module that uses (% style="color:blue" %)** ultrasonic sensing technology**(%%) for (% style="color:blue" %)**distance measurement**(%%), and (% style="color:blue" %)** temperature compensation**(%%) is performed internally to improve the reliability of data. The DDS45-LB can be applied to scenarios such as horizontal distance measurement, liquid level measurement, parking management system, object proximity and presence detection, intelligent trash can management system, robot obstacle avoidance, automatic control, sewer, bottom water level monitoring, etc.
25 +The Dragino DDS20-LB is a **LoRaWAN Ultrasonic liquid level sensor** for Internet of Things solution. It uses **none-contact method **to measure the height of liquid in a container without opening the container, and send the value via LoRaWAN network to IoT Server
21 21  
22 -It detects the distance(% style="color:blue" %)**  between the measured object and the sensor**(%%), and uploads the value via wireless to LoRaWAN IoT Server.
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 23  
24 -The LoRa wireless technology used in DDS45-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.
29 +DDS20-LB uses ultrasonic sensing technology for distance measurement. DDS20-LB is of high accuracy to measure various liquid such as: **toxic substances**, **strong acids**, **strong alkalis** and **various pure liquids** in high-temperature and high-pressure airtight containers.
