++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.
--The CPL03-LB will send periodically data every day as well as for each dry contact action. It also counts the contact open times and calculate last open duration. User can also disable the uplink for each open/close event, instead, device can count each open event and uplink periodically.
++It detects the distance(% style="color:blue" %)**  between the measured object and the sensor**(%%), and uploads the value via wireless to LoRaWAN IoT Server.
--The LoRa wireless technology used in CPL03-LB allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
