1. Introduction

1.1 What is SE0X-CB/CS NB-IoT/LTE-M Soil Moisture & EC Sensor

The Dragino SE0X-CB/CS is a NB-IoT/LTE-M Soil Moisture & EC Sensor for Agri-IoT with up to 4 sensor probes. It is designed to measure the soil moisture of saline-alkali soil and loamy soil. The soil sensor uses 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.

It detects Soil Moisture, Soil Temperature and Soil Conductivity, and then upload to IoT server via NB-IoT or CAT-M1 network.

SE0X-CB/CS supports different uplink methods include TCP, MQTT, UDP, MQTTs or CoAP for different application requirement. and Support Uplinks to various IoT Servers.

SE0X-CB/CS supports BLE configure and wireless OTA update which make user easy to use.

SE0X-CB/CS is powered by 8500mAh Li-SOCI2 battery or solar powered + Li-ion battery, it is designed for long-term use up to several years.

Main Device Dimension:

Probe Dimension:

1.9.2 for CS version

1.10 Installation in Soil

Measurement the soil surface

 ​

Choose the proper measuring position. Avoid the probe to touch rocks or hard things. Split the surface soil according to the measured deep. Keep the measured as original density. Vertical insert the probe into the soil to be measured. Make sure not shake when inserting.

Dig a hole with diameter > 20CM.

Horizontal insert the probe to the soil and fill the hole for long term measurement. 

2. Use SE0X-CB/CS to communicate with IoT Server

2.1 Send data to IoT server via NB-IoT network

The SE0X-CB/CS is equipped with a NB-IoT module, the pre-loaded firmware in SE0X-CB/CS 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 SE0X-CB/CS.

Below shows the network structure:

There are two version: -GE and -1T version of SE0X-CB/CS.

GE Version: This version doesn't include SIM card or point to any IoT server. User needs to use AT Commands to configure below two steps to set SE0X-CB/CS send data to IoT server.

• Install NB-IoT SIM card and configure APN. See instruction of Attach Network.

• Set up sensor to point to IoT Server. See instruction of Configure to Connect Different Servers.  

Below shows result of different server as a glance.

3.22 Setting the sensor address

Function:Change the sensor address to 0x01, 0x02, 0x03, 0x04

(Note:When setting the address of the sensor, you need to connect the device individually for each one, and when modifying the address, you can't connect more than one sensor at the same time, otherwise it will be impossible to modify it, and when modifying it, you need to connect the yellow wire to VDD, and after modifying it, you need to disconnect it.)

• AT+BKDNS=2,4,3.69.98.183,1883      // The dynamic domain name resolution function is enabled and the automatic update time is set to 4 hour, and manually set the ip address, if the domain name failed to resolve, it will directly use this ip to communicate. When the next domain name resolution is successful, it will be updated to the ip address of the successful resolution.
