1. Introduction
1.1 What is LoRaWAN Soil Moisture & EC Sensor
The Dragino LSE01 is a LoRaWAN Soil Moisture & EC Sensor for IoT of Agriculture. 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 uploads the value via wireless to LoRaWAN IoT Server.
The LoRa wireless technology used in LES01 allows device to send data and reach extremely long ranges at low data-rates. It provides ultra-long range spread spectrum communication and high interference immunity whilst minimizing current consumption.
LES01 is powered by 4000mA or 8500mAh Li-SOCI2 battery, It is designed for long term use up to 10 years.
Each LES01 is pre-load with a set of unique keys for LoRaWAN registrations, register these keys to local LoRaWAN server and it will auto connect after power on.

LSE01 v1.0 : Release
2. Configure LSE01 to connect to LoRaWAN network
2.1 How it works
The LSE01 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a local LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and power on the LSE0150. It will automatically join the network via OTAA and start to send the sensor value
In case you can't set the OTAA keys in the LoRaWAN OTAA server, and you have to use the keys from the server, you can use AT Commands .
2.2 Quick guide to connect to LoRaWAN server (OTAA)
Following is an example for how to join the TTN v3 LoRaWAN Network. Below is the network structure; we use the LG308 as a LoRaWAN gateway in this example.
The LG308 is already set to connected to TTN network , so what we need to now is configure the TTN server.
Step 1: Create a device in TTN with the OTAA keys from LSE01.
Each LSE01 is shipped with a sticker with the default device EUI as below:
You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:
Add APP EUI in the application
Add APP KEY and DEV EUI
Step 2: Power on LSE01
Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).
Step 3: The LSE01 will auto join to the TTN network. After join success, it will start to upload messages to TTN and you can see the messages in the panel.
2.3 Uplink Payload
2.3.1 MOD=0(Default Mode)
LSE01 will uplink payload via LoRaWAN with below payload format:
Uplink payload includes in total 11 bytes.
| Size(bytes) | 2 | 2 | 2 | 2 | 2 | 1 |
| Value | BAT | Temperature | Soil Moisture | Soil Temperature | Soil Conductivity (EC) | MOD & Digital Interrupt(Optional) |
2.3.2 MOD=1(Original value)
This mode can get the original AD value of moisture and original conductivity (with temperature drift compensation).
| Size(bytes) | 2 | 2 | 2 | 2 | 2 | 1 |
| Value | BAT | Temperature | Soil Conductivity (EC)(raw) | Soil Moisture(raw) | Dielectric constant(raw) | MOD & Digital Interrupt(Optional) |
2.3.3 Battery Info
Check the battery voltage for LSE01.
Ex1: 0x0B45 = 2885mV
Ex2: 0x0B49 = 2889mV
2.3.4 Soil Moisture
Get the moisture content of the soil. The value range of the register is 0-10000(Decimal), divide this value by 100 to get the percentage of moisture in the soil.
For example, if the data you get from the register is 0x05 0xDC, the moisture content in the soil is 05DC(H) = 1500(D) /100 = 15%.
2.3.5 Soil Temperature
Get the temperature in the soil. The value range of the register is -4000 - +800(Decimal), divide this value by 100 to get the temperature in the soil. For example, if the data you get from the register is 0x09 0xEC, the temperature content in the soil is
Example:
If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C
2.3.6 Soil Conductivity (EC)
Obtain soluble salt concentration in soil or soluble ion concentration in liquid fertilizer or planting medium. The value range of the register is 0 - 20000(Decimal)( Can be greater than 20000).
For example, if the data you get from the register is 0x00 0xC8, the soil conductivity is 00C8(H) = 200(D) = 200 uS/cm.
Generally, the EC value of irrigation water is less than 800uS / cm.
2.3.7 MOD
Firmware version at least v1.2.1 supports changing mode.
For example, bytes[10]=90
mod=(bytes[10]>>7)&0x01=1.
Downlink Command:
If payload = 0x0A00, workmode=0
If payload = 0x0A01, workmode=1
2.3.8 Decode payload in The Things Network
While using TTN network, you can add the payload format to decode the payload.
The payload decoder function for TTN is here:
LSE01 TTN Payload Decoder: https://github.com/dragino/dragino-end-node-decoder/blob/main/LSE01/LSE01_TTN%20Decoder%20V1.2.1.txt
2.4 Uplink Interval
The LSE01 by default uplink the sensor data every 20 minutes. User can change this interval by AT Command or LoRaWAN Downlink Command. See this link: Change Uplink Interval
2.5 Downlink Payload
By default, LSE01 prints the downlink payload to console port.
| Downlink Control Type | FPort | Type Code | Downlink payload size(bytes) |
|---|---|---|---|
| TDC (Transmit Time Interval) | Any | 01 | 4 |
| RESET | Any | 04 | 2 |
| AT+CFM | Any | 05 | 4 |
| INTMOD | Any | 06 | 4 |
| MOD | Any | 0A | 2 |
Examples:
Set TDC
If the payload=0100003C, it means set the END Node's TDC to 0x00003C=60(S), while type code is 01.
Payload: 01 00 00 1E TDC=30S
Payload: 01 00 00 3C TDC=60S
Reset
If payload = 0x04FF, it will reset the LSE01
- CFM
Downlink Payload: 05000001, Set AT+CFM=1 or 05000000 , set AT+CFM=0
2.6 Show Data in DataCake IoT Server
DATACAKE provides a human friendly interface to show the sensor data, once we have data in TTN, we can use DATACAKE to connect to TTN and see the data in DATACAKE. Below are the steps:
Step 1: Be sure that your device is programmed and properly connected to the network at this time.
Step 2: To configure the Application to forward data to DATACAKE you will need to add integration. To add the DATACAKE integration, perform the following steps:
Step 3: Create an account or log in Datacake.
Step 4: Search the LSE01 and add DevEUI.
After added, the sensor data arrive TTN, it will also arrive and show in Mydevices.

4. FAQ
4.1 How to change the LoRa Frequency Bands/Region?
You can follow the instructions for how to upgrade image.
When downloading the images, choose the required image file for download.
How to set up LSE01 to work in 8 channel mode By default, the frequency bands US915, AU915, CN470 work in 72 frequencies. Many gateways are 8 channel gateways, and in this case, the OTAA join time and uplink schedule is long and unpredictable while the end node is hopping in 72 frequencies.
You can configure the end node to work in 8 channel mode by using the AT+CHE command. The 500kHz channels are always included for OTAA.
For example, in US915 band, the frequency table is as below. By default, the end node will use all channels (0~71) for OTAA Join process. After the OTAA Join, the end node will use these all channels (0~71) to send uplink packets.
| CHE | US915 Uplink Channels(125KHz,4/5,Unit:MHz,CHS=0) | ||||||||
| 0 | ENABLE Channel 0-63 | ||||||||

When you use the TTN network, the US915 frequency bands use are:
- 903.9 - SF7BW125 to SF10BW125
- 904.1 - SF7BW125 to SF10BW125
- 904.3 - SF7BW125 to SF10BW125
- 904.5 - SF7BW125 to SF10BW125
- 904.7 - SF7BW125 to SF10BW125
- 904.9 - SF7BW125 to SF10BW125
- 905.1 - SF7BW125 to SF10BW125
- 905.3 - SF7BW125 to SF10BW125
- 904.6 - SF8BW500
Because the end node is now hopping in 72 frequency, it makes it difficult for the devices to Join the TTN network and uplink data. To solve this issue, you can access the device via the AT commands and run:
- AT+CHE=2
- ATZ
to set the end node to work in 8 channel mode. The device will work in Channel 8-15 & 64-71 for OTAA, and channel 8-15 for Uplink.
The AU915 band is similar. Below are the AU915 Uplink Channels.

4.2 Can I calibrate LSE01 to different soil types?
LSE01 is calibrated for saline-alkali soil and loamy soil. If users want to use it for other soil, they can calibrate the value in the IoT platform base on the value measured by saline-alkali soil and loamy soil. The formula can be found at this link.
5. Trouble Shooting
5.1 Why I can't join TTN in US915 / AU915 bands?
It is due to channel mapping. Please see the Eight Channel Mode section above for details.
5.2 AT Command input doesn't work
In the case if user can see the console output but can't type input to the device. Please check if you already include the ENTER while sending out the command. Some serial tool doesn't send ENTER while press the send key, user need to add ENTER in their string.
5.3 Device rejoin in at the second uplink packet
Issue describe as below:
Cause for this issue:
The fuse on LSE01 is not large enough, some of the soil probe require large current up to 5v 800mA, in a short pulse. When this happen, it cause the device reboot so user see rejoin.
Solution:
All new shipped LSE01 after 2020-May-30 will have this to fix. For the customer who see this issue, please bypass the fuse as below:
5.3 Possible reasons why the device is unresponsive：
1. Check whether the battery voltage is lower than 2.8V
2. Check whether the jumper of the device is correctly connected
3. Check whether the switch here of the device is at the ISP（The switch can operate normally only when it is in RUN）
5.4 The node cannot read the sensor data
This may be caused by a software firmware(≤1.1.6 version) bug, which we fixed in the latest firmware (>1.1.6 version)
The user can fix this problem via upgrade firmware.
By default, The latest firmware value of POWERIC is 1, while the 3322 version requires POWERIC to be set to 0 in order to function properly
- 1. Check if the hardware version is 3322
If the sensor hardware version is 3322 or earlier, the user can change the POWERIC value to 0 after a firmware upgrade using one of the following methods
a. Using AT command
b. Using Downlink
Please check your hardware production date
The first two digits are the week of the year, and the last two digits are the year.
The number 3322 is the first batch we changed the power IC.
