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.

226
227 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.
228
229 For example, if the data you get from the register is __0x05 0xDC__, the moisture content in the soil is
230
231
232 (% style="color:#4f81bd" %)**05DC(H) = 1500(D) /100 = 15%.**
233

237
238 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
239
240 **Example**:
241
242 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
243
244 If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C

274 For example, bytes[10]=90
275
276 mod=(bytes[10]>>7)&0x01=1.

287 === 2.3.8 ​Decode payload in The Things Network ===
288
289 While using TTN network, you can add the payload format to decode the payload.

297
298
299
300 == 2.4 Uplink Interval ==
301
302 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"]]
303
304
305
306 == 2.5 Downlink Payload ==

312
313 **Examples:**
314
315
316 * **Set TDC**
317
318 If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
319
320 Payload:    01 00 00 1E    TDC=30S
321
322 Payload:    01 00 00 3C    TDC=60S
323
324
325 * **Reset**
326
327 If payload = 0x04FF, it will reset the LSE01
328
329
330 * **CFM**
331
332 Downlink Payload: 05000001, Set AT+CFM=1 or 05000000 , set AT+CFM=0

336 == 2.6 ​Show Data in DataCake IoT Server ==
337
338 [[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:
339
340
341 **Step 1**: Be sure that your device is programmed and properly connected to the network at this time.
342
343 **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:
344
345
346 [[image:1654505857935-743.png]]
347
348
349 [[image:1654505874829-548.png]]
350
351 Step 3: Create an account or log in Datacake.
352
353 Step 4: Search the LSE01 and add DevEUI.
354
355
356 [[image:1654505905236-553.png]]
357
358
359 After added, the sensor data arrive TTN, it will also arrive and show in Mydevices.
