26 -The Dragino DDS45-NB is a (% style="color:blue" %)** NB-IoT 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 distance measurement, and (% style="color:blue" %)** temperature compensation**(%%) is performed internally to improve the reliability of data. The DDS45-NB 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 +The Dragino DDS20-NB is a (% style="color:blue" %)**NB-IoT 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 IoT platform via NB-IoT network.
