20 -The Dragino S31-NB and S31B-NB are (% style="color:blue" %)**NB-IoT Temperature and Humidity Sensor**(%%) for Internet of Things solution. It is used to measure the surrounding (% style="color:blue" %)**environment temperature and relative air humidity precisely**(%%), and then upload to IoT server via NB-IoT network*.
19 +The Dragino DDS20-NB is a **NB-IoT Ultrasonic liquid level sensor** for Internet of Things solution. It uses **none-contact method **to measure the **height of liquid** in a container without opening the container, and send IoT platform via NB-IoT network.
21 21  
22 -The temperature & humidity sensor used in S31-NB is SHT31, which is fully calibrated, linearized, and temperature compensated digital output from Sensirion, it provides a strong reliability and long-term stability. The SHT31 is fixed in a (% style="color:blue" %)**waterproof anti-condensation casing**(%%) for long term use.
21 +The DDS20-NB sensor is installed directly below the container to detect the height of the liquid level. User doesn't need to open a hole on the container to be tested. The none-contact measurement makes the measurement safety, easier and possible for some strict situation.

24 -S31-NB supports different uplink methods include (% style="color:blue" %)**TCP, MQTT, UDP**(%%) for different application requirement. and Support Uplinks to various IoT Servers.
23 +DDS20-NB uses **ultrasonic sensing technology** for distance measurement. DDS20-NB is of high accuracy to measure various liquid such as: **toxic substances**, **strong acids**, **strong alkalis** and **various pure liquids** in high-temperature and high-pressure airtight containers.
25 25  
26 -S31-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), It is designed for long term use up to several years. (Real-world battery life depends on the use environment, update period and uplink method. Please check related Power Analyze report).
