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="H3.200BUsingtheATCommands"]].

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:

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.

208
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

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

252 === 2.3.7 MOD ===
253
254 Firmware version at least v2.1 supports changing mode.

256 For example, bytes[10]=90
257
258 mod=(bytes[10]>>7)&0x01=1.

265 If** **payload =** **0x0A01, workmode=1
266
267
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
282 == 2.4 Uplink Interval ==
283
284 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"]]
285
286
287
288 == 2.5 Downlink Payload ==
289
290 By default, LSE50 prints the downlink payload to console port.

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

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