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:

116 **Add APP EUI in the application**

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.

221
222 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.
223
224 For example, if the data you get from the register is __0x05 0xDC__, the moisture content in the soil is
225
226
227 (% style="color:#4f81bd" %)**05DC(H) = 1500(D) /100 = 15%.**
228

230
231 === 2.3.5 Soil Temperature ===
232
233 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
234
235 **Example**:
236
237 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
238
239 If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C

269 For example, bytes[10]=90
270
271 mod=(bytes[10]>>7)&0x01=1.

281
282 === 2.3.8 ​Decode payload in The Things Network ===
283
284 While using TTN network, you can add the payload format to decode the payload.
285
286
287 [[image:1654505570700-128.png]]

292
293
294
295 == 2.4 Uplink Interval ==
296
297 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"]]
298
299
300
301 == 2.5 Downlink Payload ==
302
303 By default, LSE50 prints the downlink payload to console port.

307
308 **Examples:**
309
310
311 * **Set TDC**
312
313 If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
314
315 Payload:    01 00 00 1E    TDC=30S
316
317 Payload:    01 00 00 3C    TDC=60S
318
319
320 * **Reset**
321
322 If payload = 0x04FF, it will reset the LSE01
323
324
325 * **CFM**
326
327 Downlink Payload: 05000001, Set AT+CFM=1 or 05000000 , set AT+CFM=0

331 == 2.6 ​Show Data in DataCake IoT Server ==
332
333 [[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:
334
335
336 **Step 1**: Be sure that your device is programmed and properly connected to the network at this time.
337
338 **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:
339
340
341 [[image:1654505857935-743.png]]
342
343
344 [[image:1654505874829-548.png]]
345
346 Step 3: Create an account or log in Datacake.
347
348 Step 4: Search the LSE01 and add DevEUI.
349
350
351 [[image:1654505905236-553.png]]
352
353
354 After added, the sensor data arrive TTN, it will also arrive and show in Mydevices.
