25 == 1.1 What is NB-IoT Soil Moisture & EC Sensor ==
26
27
28 The Dragino SE01-NB is a (% style="color:blue" %)**NB-IoT Soil Moisture & EC Sensor**(%%) for IoT of Agriculture. It is designed to measure the (% style="color:blue" %)**soil moisture of saline-alkali soil and loamy soil**(%%). The soil sensor uses (% style="color:blue" %)**FDR method**(%%) to calculate the soil moisture with the compensation from soil temperature and conductivity. It also has been calibrated in factory for Mineral soil type.
29
30 It detects (% style="color:blue" %)**Soil Moisture**(%%), (% style="color:blue" %)**Soil Temperature**(%%) and (% style="color:blue" %)**Soil Conductivity**(%%), and uploads the value via wireless to NB-IoT IoT Server.
31
32 SE01-NB supports different uplink methods including (% style="color:blue" %)**MQTT, MQTTs, UDP & TCP**(%%) for different application requirement, and support uplinks to various IoT Servers.
33
34 SE01-NB (% style="color:blue" %)**supports BLE configure and OTA update**(%%) which make user easy to use.
35
36 SE01-NB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long-term use up to several years.
37
38 SE01-NB has optional built-in SIM card and default IoT server connection version. Which makes it works with simple configuration.
