23 The Dragino LDDS45 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 LDDS45 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.

If there is coverage of the LoRaWAN network, it will automatically join the network via OTAA and start to send the sensor value
