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.
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.**
