17 == 1.1 ​What is LoRaWAN Soil Moisture & EC Sensor ==
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.

86 == 2.1 How it works ==
87
88 (((
89 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
90 )))
91
92 (((
93 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"]].

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

125
126 [[image:1654504683289-357.png]]
127
128
129
130 **Step 2**: Power on LSE01
131
132
133 Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).
134
135 [[image:image-20220606163915-7.png]]
136
137
138 **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.

206 === 2.3.4 Soil Moisture ===
207
208 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.
209
210 For example, if the data you get from the register is __0x05 0xDC__, the moisture content in the soil is
211
212
213 (% style="color:#4f81bd" %)**05DC(H) = 1500(D) /100 = 15%.**
214
215
216
217 === 2.3.5 Soil Temperature ===
218
219 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
220
221 **Example**:
222
223 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
224
225 If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C

250
251 === 2.3.7 MOD ===
252
253 Firmware version at least v2.1 supports changing mode.
254
255 For example, bytes[10]=90
256
257 mod=(bytes[10]>>7)&0x01=1.
258
259
260 **Downlink Command:**
261

264 If** **payload =** **0x0A01, workmode=1
265
266
267
268 === 2.3.8 ​Decode payload in The Things Network ===
269
270 While using TTN network, you can add the payload format to decode the payload.
271
272
273 [[image:1654505570700-128.png]]
274
275 The payload decoder function for TTN is here:

278
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>>doc:Main.End Device AT Commands and Downlink Command.WebHome||anchor="H4.1ChangeUplinkInterval"]]
284
285
286
287 == 2.5 Downlink Payload ==
288
289 By default, LSE50 prints the downlink payload to console port.

292
293
294 **Examples:**
295
296
297 * **Set TDC**
298
299 If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
300
301 Payload:    01 00 00 1E    TDC=30S
302
303 Payload:    01 00 00 3C    TDC=60S
304
305
306 * **Reset**
307
308 If payload = 0x04FF, it will reset the LSE01
309
310
311 * **CFM**
312
313 Downlink Payload: 05000001, Set AT+CFM=1 or 05000000 , set AT+CFM=0

317 == 2.6 ​Show Data in DataCake IoT Server ==
318
319 [[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:
320
321
322 **Step 1**: Be sure that your device is programmed and properly connected to the network at this time.
323
324 **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:
325
326
327 [[image:1654505857935-743.png]]
328
329
330 [[image:1654505874829-548.png]]
331
332 Step 3: Create an account or log in Datacake.
333
334 Step 4: Search the LSE01 and add DevEUI.
335
336
337 [[image:1654505905236-553.png]]
338
339
340 After added, the sensor data arrive TTN, it will also arrive and show in Mydevices.
