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
20 +The Dragino DDS45-LB is a (% style="color:blue" %)** LoRaWAN Distance Detection Sensor**(%%) for Internet of Things solution.
