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.

89
90 (((
91 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
92 )))
93
94 (((
95 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"]].

100 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
101
102 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.
103
104
105 [[image:1654503992078-669.png]]
106
107
108 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.
109
110
111 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
112
113 Each LSE01 is shipped with a sticker with the default device EUI as below:
114
115 [[image:image-20220606163732-6.jpeg]]
116
117 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:
118
119 **Add APP EUI in the application**

127
128 [[image:1654504683289-357.png]]
129
130
131
132 **Step 2**: Power on LSE01
133
134
135 Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).
136
137 [[image:image-20220606163915-7.png]]
138
139
140 **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.

237
238 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.
239
240 For example, if the data you get from the register is __0x05 0xDC__, the moisture content in the soil is
241
242
243 (% style="color:#4f81bd" %)**05DC(H) = 1500(D) /100 = 15%.**
244

250
251 **Example**:
252
253 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C

308
309
310
311 == 2.4 Uplink Interval ==
312
313 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"]]
314
315

323
324 **Examples:**
325
326
327 * **Set TDC**
328
329 If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
330
331 Payload:    01 00 00 1E    TDC=30S
332
333 Payload:    01 00 00 3C    TDC=60S
334
335
336 * **Reset**
337
338 If payload = 0x04FF, it will reset the LSE01
339
340
341 * **CFM**
342
343 Downlink Payload: 05000001, Set AT+CFM=1 or 05000000 , set AT+CFM=0

347 == 2.6 ​Show Data in DataCake IoT Server ==
348
349 [[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:
350
351
352 **Step 1**: Be sure that your device is programmed and properly connected to the network at this time.
353
354 **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:
355
356
357 [[image:1654505857935-743.png]]
358
359
360 [[image:1654505874829-548.png]]
361
362 Step 3: Create an account or log in Datacake.
363
364 Step 4: Search the LSE01 and add DevEUI.
365
366
367 [[image:1654505905236-553.png]]
368
369
370 After added, the sensor data arrive TTN, it will also arrive and show in Mydevices.
