++== 1.1 What is S31x-NB NB-IoT Temperature & Humidity Sensor ==
--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 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 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.
++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.
--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 supports different uplink methods include (% style="color:blue" %)**TCP, MQTT, UDP** for different application requirement. and Support Uplinks to various IoT Servers.
--PS-NB-NA supports different uplink methods including **MQTT, MQTTs, UDP & TCP** for different application requirement, and support uplinks to various IoT Servers.
++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 BLE configure **and** OTA update** which make user easy to use.
++*make sure you have NB-IoT coverage locally.
--PS-NB-NA is powered by **8500mAh Li-SOCI2 battery**, it is designed for long-term use up to severa years.
--PS-NB-NA has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
