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.
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.
