24	24	The Dragino LDDS75 is a (% style="color:#4472c4" %)** 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:#4472c4" %)** ultrasonic sensing** (%%)technology for distance measurement, and (% style="color:#4472c4" %)** temperature compensation**(%%) is performed internally to improve the reliability of data. The LDDS75 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.
