14
15 (((
16 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.
17 )))
18
19 (((
20 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.
21 )))
22
23 (((
24 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.
25 )))
26
27 (((
28 LES01 is powered by (% style="color:#4f81bd" %)**4000mA or 8500mAh Li-SOCI2 battery**(%%), It is designed for long term use up to 10 years.
29 )))
30
31 (((
32 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.

81 == 2.1 How it works ==
82
83 (((
84 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
85 )))
86
87 (((
88 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"]].

92
93 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
94
95 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.
96
97
98 [[image:1654503992078-669.png]]
99
100
101 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.
102
103
104 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
105
106 Each LSE01 is shipped with a sticker with the default device EUI as below:
107
108 [[image:image-20220606163732-6.jpeg]]
109
110 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

120
121 [[image:1654504683289-357.png]]
122
123
124
125 **Step 2**: Power on LSE01
126
127
128 Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).
129
130 [[image:image-20220606163915-7.png]]
131
132
133 **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.

201 === 2.3.4 Soil Moisture ===
202
203 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.
204
205 For example, if the data you get from the register is __0x05 0xDC__, the moisture content in the soil is
206
207
208 (% style="color:#4f81bd" %)**05DC(H) = 1500(D) /100 = 15%.**
209
210
211
212 === 2.3.5 Soil Temperature ===
213
214 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
215
216 **Example**:
217
218 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
219

250 For example, bytes[10]=90
251
252 mod=(bytes[10]>>7)&0x01=1.

259 If** **payload =** **0x0A01, workmode=1
260
261
262
263 === 2.3.8 ​Decode payload in The Things Network ===
264
265 While using TTN network, you can add the payload format to decode the payload.
266
267
268 [[image:1654505570700-128.png]]
269
270 The payload decoder function for TTN is here:

273
274
275 == 2.4 Uplink Interval ==
276
277 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:
278
279 [[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]]
280
281
282
283 == 2.5 Downlink Payload ==
284
285 By default, LSE50 prints the downlink payload to console port.
286
287 [[image:image-20220606165544-8.png]]
288
289
290 **Examples:**
291
292
293 * **Set TDC**
294
295 If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
296
297 Payload:    01 00 00 1E    TDC=30S
298
299 Payload:    01 00 00 3C    TDC=60S
300
301
302 * **Reset**
303
304 If payload = 0x04FF, it will reset the LSE01
305
306
307 * **CFM**
308
309 Downlink Payload: 05000001, Set AT+CFM=1 or 05000000 , set AT+CFM=0

312
313 == 2.6 ​Show Data in DataCake IoT Server ==
314
315 [[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:
316
317
318 **Step 1**: Be sure that your device is programmed and properly connected to the network at this time.
319
320 **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:
321
322
323 [[image:1654505857935-743.png]]
324
325
326 [[image:1654505874829-548.png]]
327
328 Step 3: Create an account or log in Datacake.
329
330 Step 4: Search the LSE01 and add DevEUI.
331
332
333 [[image:1654505905236-553.png]]
334
335
336 After added, the sensor data arrive TTN, it will also arrive and show in Mydevices.

859 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.
860
861
862 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.
863
864
865 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.
866
867 [[image:image-20220606154726-3.png]]
868
869 When you use the TTN network, the US915 frequency bands use are:
870
871 * 903.9 - SF7BW125 to SF10BW125
872 * 904.1 - SF7BW125 to SF10BW125
873 * 904.3 - SF7BW125 to SF10BW125
874 * 904.5 - SF7BW125 to SF10BW125
875 * 904.7 - SF7BW125 to SF10BW125
876 * 904.9 - SF7BW125 to SF10BW125
877 * 905.1 - SF7BW125 to SF10BW125
878 * 905.3 - SF7BW125 to SF10BW125
879 * 904.6 - SF8BW500
880
881 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:
882
883 (% class="box infomessage" %)
884 (((
885 **AT+CHE=2**
886 )))
887
888 (% class="box infomessage" %)
889 (((
890 **ATZ**
891 )))
892
893 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.
894
895
896 The **AU915** band is similar. Below are the AU915 Uplink Channels.
