25 -The Dragino SW3L-NB is a NB-IoT Flow Sensor. It detects water flow volume and uplink to IoT server via NB-IoT network. User can use this to monitor the water usage for buildings.
26 +The Dragino DDS45-NB is a (% style="color:blue" %)** NB-IoT 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 distance measurement, and (% style="color:blue" %)** temperature compensation**(%%) is performed internally to improve the reliability of data. The DDS45-NB 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.
26 26  
27 -The SW3L-NB will send water flow volume every 20 minutes. It can also detect the water flow status and send Alarm, to avoid the waste for water usage such as broken toilet case.
28 +It detects the distance (% style="color:blue" %)** between the measured object and the sensor**(%%), and and send IoT platform via NB-IoT network.
28 28  
29 -SW3L-NB is designed for both indoor and outdoor use. It has a weatherproof enclosure and industrial level battery to work in low to high temperatures.
30 +DDS45-NB supports different uplink methods including (% style="color:blue" %)**MQTT, MQTTs, UDP & TCP**(%%) for different application requirement, and support uplinks to various IoT Servers.
