18
19 (((
20 The Dragino LSE01 is a (% style="color:#4f81bd" %)**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.
21 )))
22
23 (((
24 It detects (% style="color:#4f81bd" %)**Soil Moisture**(%%), (% style="color:#4f81bd" %)**Soil Temperature**(%%) and (% style="color:#4f81bd" %)**Soil Conductivity**(%%), and uploads the value via wireless to LoRaWAN IoT Server.
25 )))
26
27 (((
28 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.
29 )))
30
31 (((
32 LES01 is powered by (% style="color:#4f81bd" %)**4000mA or 8500mAh Li-SOCI2 battery**(%%), It is designed for long term use up to 10 years.
33 )))
34
35 (((
36 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.

85 == 2.1 How it works ==
86
87 (((
88 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
89 )))
90
91 (((
92 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 >>||anchor="H3.​UsingtheATCommands"]].

96
97 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
98
99 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.
100
101
102 [[image:1654503992078-669.png]]
103
104
105 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.
106
107
108 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
109
110 Each LSE01 is shipped with a sticker with the default device EUI as below:
111
112 [[image:image-20220606163732-6.jpeg]]
113
114 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

116 **Add APP EUI in the application**

124
125 [[image:1654504683289-357.png]]
126
127
128
129 **Step 2**: Power on LSE01
130
131
132 Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).
133
134 [[image:image-20220606163915-7.png]]
135
136
137 **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.

209 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.
210
211 For example, if the data you get from the register is __0x05 0xDC__, the moisture content in the soil is
212
213
214 (% style="color:#4f81bd" %)**05DC(H) = 1500(D) /100 = 15%.**
215

221
222 **Example**:
223
224 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C

268
269 === 2.3.8 ​Decode payload in The Things Network ===
270
271 While using TTN network, you can add the payload format to decode the payload.
272
273
274 [[image:1654505570700-128.png]]
275
276 The payload decoder function for TTN is here:

279
280
281 == 2.4 Uplink Interval ==
282
283 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>>End Device AT Commands and Downlink Command||anchor="H4.1ChangeUplinkInterval"]]
284
285 [[http:~~/~~/wiki.dragino.com/index.php?title=End_Device_AT_Commands_and_Downlink_Commands#Change_Uplink_Interval>>url:http://wiki.dragino.com/index.php?title=End_Device_AT_Commands_and_Downlink_Commands#Change_Uplink_Interval]]
286

288
289 == 2.5 Downlink Payload ==
290
291 By default, LSE50 prints the downlink payload to console port.

294
295
296 **Examples:**
297
298
299 * **Set TDC**
300
301 If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
302
303 Payload:    01 00 00 1E    TDC=30S
304
305 Payload:    01 00 00 3C    TDC=60S
306
307
308 * **Reset**
309
310 If payload = 0x04FF, it will reset the LSE01
311
312
313 * **CFM**
314
315 Downlink Payload: 05000001, Set AT+CFM=1 or 05000000 , set AT+CFM=0

318
319 == 2.6 ​Show Data in DataCake IoT Server ==
320
321 [[DATACAKE>>url:https://datacake.co/]] provides a human friendly interface to show the sensor data, once we have data in TTN, we can use [[DATACAKE>>url:https://datacake.co/]] to connect to TTN and see the data in DATACAKE. Below are the steps:
322
323
324 **Step 1**: Be sure that your device is programmed and properly connected to the network at this time.
325
326 **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:
327
328
329 [[image:1654505857935-743.png]]
330
331
332 [[image:1654505874829-548.png]]
333
334 Step 3: Create an account or log in Datacake.
335
336 Step 4: Search the LSE01 and add DevEUI.
337
338
339 [[image:1654505905236-553.png]]
340
341
342 After added, the sensor data arrive TTN, it will also arrive and show in Mydevices.

885
886 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.
887
888
889 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.
890
891
892 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.
893
894 [[image:image-20220606154726-3.png]]
895
896 When you use the TTN network, the US915 frequency bands use are:
897
898 * 903.9 - SF7BW125 to SF10BW125
899 * 904.1 - SF7BW125 to SF10BW125
900 * 904.3 - SF7BW125 to SF10BW125
901 * 904.5 - SF7BW125 to SF10BW125
902 * 904.7 - SF7BW125 to SF10BW125
903 * 904.9 - SF7BW125 to SF10BW125
904 * 905.1 - SF7BW125 to SF10BW125
905 * 905.3 - SF7BW125 to SF10BW125
906 * 904.6 - SF8BW500
907
908 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:
909
910 (% class="box infomessage" %)
911 (((
912 **AT+CHE=2**
913 )))
914
915 (% class="box infomessage" %)
916 (((
917 **ATZ**
918 )))
919
920 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.
921
922
923 The **AU915** band is similar. Below are the AU915 Uplink Channels.
