21 -The Dragino SW3L-LB is a (% style="color:blue" %)**LoRaWAN Flow Sensor**(%%). It detects water flow volume and uplink to IoT server via LoRaWAN network. User can use this to(% style="color:blue" %)** monitor the water usage for buildings.**
21 +The Dragino DDS75-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 DDS75-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.
