	23	1. Introduction
	24	11. What is LoRaWAN Soil Moisture & EC Sensor
	25
	26	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.
	27
	28
	29	It detects Soil Moisture, Soil Temperature and Soil Conductivity, and uploads the value via wireless to LoRaWAN IoT Server.
	30
	31
	32	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.
	33
	34
	35	LES01 is powered by 4000mA or 8500mAh Li-SOCI2 battery, It is designed for long term use up to 10 years.
	36
	37
	38	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.

	101	1. Configure LSE01 to connect to LoRaWAN network
	102	11. How it works
	103
	104	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
	105
	106
	107	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 >>path:#_Using_the_AT]]to set the keys in the LSE01.

4.2	113	11. Quick guide to connect to LoRaWAN server (OTAA)
	114
	115	Following is an example for how to join the [[TTN v3 LoRaWAN Network>>url:https://console.cloud.thethings.network/]]. Below is the network structure; we use the [[LG308>>url:http://www.dragino.com/products/lora/item/140-lg308.html]] as a LoRaWAN gateway in this example.
	116
	117
	118	[[image:file:///C:/Users/93456/AppData/Local/Temp/msohtmlclip1/01/clip_image003.png]]
	119
	120
	121	The LG308 is already set to connected to [[TTN network >>url:https://console.cloud.thethings.network/]], so what we need to now is configure the TTN server.
	122
	123
	124	Step 1: Create a device in TTN with the OTAA keys from LSE01.
	125
	126	Each LSE01 is shipped with a sticker with the default device EUI as below:
	127
	128
	129
	130
	131	You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:
	132
	133
	134	Add APP EUI in the application

	149
	150
	151	Step 2: Power on LSE01
	152
	153
	154	Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).

	163
	164
	165
	166
	167
	168	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.

4.4	238	1.
	239	11.
4.2	240	111. Soil Moisture
	241
	242	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.
	243
	244	For example, if the data you get from the register is 0x05 0xDC, the moisture content in the soil is
	245
	246	05DC(H) = 1500(D) /100 = 15%.
	247
	248
4.4	249	1.
	250	11.
4.2	251	111. Soil Temperature
	252
	253	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
	254
	255	Example:
	256
	257	If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
	258
	259	If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C

4.2	264	111. Soil Conductivity (EC)
	265
	266	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).
	267
	268	For example, if the data you get from the register is 0x00 0xC8, the soil conductivity is 00C8(H) = 200(D) = 200 uS/cm.
	269
	270

	723	111. Battery Type
	724
	725	The LSE01 battery is a combination of a 4000mAh Li/SOCI2 Battery and a Super Capacitor. The battery is non-rechargeable battery type with a low discharge rate (<2% per year). This type of battery is commonly used in IoT devices such as water meter.
	726
	727
	728	The battery is designed to last for more than 5 years for the LSN50.
	729
	730
	731	The battery related documents as below:

4.2	747	111. Battery Note
	748
	749	The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased.

4.2	754	111. Replace the battery
	755
	756	If Battery is lower than 2.7v, user should replace the battery of LSE01.
	757
	758
	759	You can change the battery in the LSE01.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.
	760
	761
	762	The default battery pack of LSE01 includes a ER18505 plus super capacitor. If user can’t find this pack locally, they can find ER18505 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes)

4.2	905
6.3	906	== 4.1 How to change the LoRa Frequency Bands/Region? ==
	907
4.2	908	You can follow the instructions for [[how to upgrade image>>path:#3ygebqi]].
	909	When downloading the images, choose the required image file for download.
	910
	911
8.3	912	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.
4.2	913
	914
	915	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.
	916
	917
	918	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.
	919
8.2	920	[[image:image-20220606154726-3.png]]
4.2	921
	922	When you use the TTN network, the US915 frequency bands use are:
	923
	924	* 903.9 - SF7BW125 to SF10BW125
	925	* 904.1 - SF7BW125 to SF10BW125
	926	* 904.3 - SF7BW125 to SF10BW125
	927	* 904.5 - SF7BW125 to SF10BW125
	928	* 904.7 - SF7BW125 to SF10BW125
	929	* 904.9 - SF7BW125 to SF10BW125
	930	* 905.1 - SF7BW125 to SF10BW125
	931	* 905.3 - SF7BW125 to SF10BW125
	932	* 904.6 - SF8BW500
	933
8.3	934
4.2	935	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:
	936
8.3	937	(% class="box infomessage" %)
	938	(((
4.2	939	AT+CHE=2
8.3	940	)))
4.2	941
8.3	942	(% class="box infomessage" %)
	943	(((
4.2	944	ATZ
8.3	945	)))
4.2	946
	947	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.
	948
	949
	950	The AU915 band is similar. Below are the AU915 Uplink Channels.

4.2	957
4.9	958	== 5.1 Why I can’t join TTN in US915 / AU915 bands? ==
	959
4.11	960	It is due to channel mapping. Please see the [[Eight Channel Mode>>doc:Main.LoRaWAN Communication Debug.WebHome\|\|anchor="H2.NoticeofUS9152FCN4702FAU915Frequencyband"]] section above for details.
