--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*.
++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.
--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.
++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.
--S31-NB supports different uplink methods include (% style="color:blue" %)**TCP, MQTT, UDP** for different application requirement. and Support Uplinks to various IoT Servers.
++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.
--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).
++PS-NB-NA supports different uplink methods including **MQTT, MQTTs, UDP & TCP** for different application requirement, and support uplinks to various IoT Servers.
--*make sure you have NB-IoT coverage locally.
++PS-NB-NA **supports BLE configure **and** OTA update** which make user easy to use.

++
++
++* At room temperature, containers of different materials, such as steel, glass, iron, ceramics, non-foamed plastics and other dense materials, have different detection blind areas and detection limit heights.
++
++* For containers of the same material at room temperature, the detection blind zone and detection limit height are also different for the thickness of the container.
++
++* When the detected liquid level exceeds the effective detection value of the sensor, and the liquid level of the liquid to be measured shakes or tilts, the detected liquid height is unstable.
