NSE01 - NB-IoT Soil Moisture & EC Sensor User Manual

Dragino NSE01 is an (% style="color:blue" %)**NB-IOT soil moisture & EC sensor**(%%) for agricultural IoT. Used to measure the soil moisture of saline-alkali soil and loam. The soil sensor uses the FDR method to calculate soil moisture and compensates it with soil temperature and electrical conductivity. It has also been calibrated for mineral soil types at the factory.

31

32

It can detect (% style="color:blue" %)**Soil Moisture, Soil Temperature and Soil Conductivity**(%%), and upload its value to the server wirelessly.

33

34

The wireless technology used in NSE01 allows the device to send data at a low data rate and reach ultra-long distances, providing ultra-long-distance spread spectrum Communication.

35

36

NSE01 are powered by (% style="color:blue" %)**8500mAh Li-SOCI2**(%%) batteries, which can be used for up to 5 years.

== 2.1 How it works ==

(((

The NSE01 is equipped with a NB-IoT module, the pre-loaded firmware in NSE01 will get environment data from sensors and send the value to local NB-IoT network via the NB-IoT module. The NB-IoT network will forward this value to IoT server via the protocol defined by NSE01.

To use NSE01 in your city, make sure meet below requirements:

138

139

* Your local operator has already distributed a NB-IoT Network there.

140

* The local NB-IoT network used the band that NSE01 supports.

141

* Your operator is able to distribute the data received in their NB-IoT network to your IoT server.

468

469

NSE01 will enable +5V output before all sampling and disable the +5v after all sampling.

The default battery pack of NSE01 includes a ER26500 plus super capacitor. If user can't find this pack locally, they can find ER26500 or equivalence without the SPC1520 capacitor, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes).
