32 The Dragino NSE01 is a (% style="color:blue" %)**NB-IOT soil moisture & EC sensor**(%%) designed for IoT of Agriculture. It detects Soil Moisture, Soil Temperature and Soil Conductivity, and upload the value via wireless to IoT Server via NB-IoT Network.
33 \\NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services. NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.
34 \\NSE01 supports different uplink methods include (% style="color:blue" %)**TCP,MQTT,UDP and CoAP **(%%)** **for different application requirement.
35 \\NES01 is powered by  (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), It is designed for long term use up to 5 years. (Actually Battery life depends on the use environment, update period & uplink method)
36 \\To use NSE01, user needs to check if there is NB-IoT coverage in local area and with the bands NSE01 supports. If the local operate support it, user needs to get a (% style="color:blue" %)**NB-IoT SIM card**(%%) from local operator and install NSE01 to get NB-IoT network connection.
