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.

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.

87 == 2.1 How it works ==
88
89 (((
90 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
91 )))
92
93 (((
94 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="H3.200BUsingtheATCommands"]].

99 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
100
101 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.
102
103
104 [[image:1654503992078-669.png]]
105
106
107 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.
108
109
110 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
111
112 Each LSE01 is shipped with a sticker with the default device EUI as below:
113
114 [[image:image-20220606163732-6.jpeg]]
115
116 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

126
127 [[image:1654504683289-357.png]]
128
129
130
131 **Step 2**: Power on LSE01
132
133
134 Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).
135
136 [[image:image-20220606163915-7.png]]
137
138
139 **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.

210
211 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.
212
213 For example, if the data you get from the register is __0x05 0xDC__, the moisture content in the soil is
214
215
216 (% style="color:#4f81bd" %)**05DC(H) = 1500(D) /100 = 15%.**
217

220 === 2.3.5 Soil Temperature ===
221
222 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
223
224 **Example**:
225
226 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
227
228 If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C

254 === 2.3.7 MOD ===
255
256 Firmware version at least v2.1 supports changing mode.

258 For example, bytes[10]=90
259
260 mod=(bytes[10]>>7)&0x01=1.

270
271 === 2.3.8 ​Decode payload in The Things Network ===
272
273 While using TTN network, you can add the payload format to decode the payload.
274
275
276 [[image:1654505570700-128.png]]
277
278 The payload decoder function for TTN is here:

281
282
283
284 == 2.4 Uplink Interval ==
285
286 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>>doc:Main.End Device AT Commands and Downlink Command.WebHome||anchor="H4.1ChangeUplinkInterval"]]
287
288
289
290 == 2.5 Downlink Payload ==
291
292 By default, LSE50 prints the downlink payload to console port.

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

320 == 2.6 ​Show Data in DataCake IoT Server ==
321
322 [[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:
323
324
325 **Step 1**: Be sure that your device is programmed and properly connected to the network at this time.
326
327 **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:
328
329
330 [[image:1654505857935-743.png]]
331
332
333 [[image:1654505874829-548.png]]
334
335 Step 3: Create an account or log in Datacake.
336
337 Step 4: Search the LSE01 and add DevEUI.
338
339
340 [[image:1654505905236-553.png]]
341
342
343 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**

914

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
