15 (((
16 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.

19 (((
20 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.
21 )))
22
23 (((
24 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.

27 (((
28 LES01 is powered by (% style="color:#4f81bd" %)**4000mA or 8500mAh Li-SOCI2 battery**(%%), It is designed for long term use up to 10 years.

84
85 (((
86 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 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.​UsingtheATCommands"]].

95 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
96
97 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.
98
99
100 [[image:1654503992078-669.png]]
101
102
103 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.
104
105
106 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
107
108 Each LSE01 is shipped with a sticker with the default device EUI as below:
109
110

113 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

209 111. Battery Info
210
211 Check the battery voltage for LSE01.
212
213 Ex1: 0x0B45 = 2885mV
214
215 Ex2: 0x0B49 = 2889mV

220 11.
221 111. Soil Moisture
222
223 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.
224
225 For example, if the data you get from the register is 0x05 0xDC, the moisture content in the soil is
226
227 **05DC(H) = 1500(D) /100 = 15%.**
228
229
230 1.
231 11.
232 111. Soil Temperature
233
234 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
235
236 **Example**:
237
238 If payload is 0105H: ((0x0105 & 0x8000)>>15 === 0),temp = 0105(H)/100 = 2.61 °C
239
240 If payload is FF7EH: ((FF7E & 0x8000)>>15 ===1),temp = (FF7E(H)-FFFF(H))/100 = -1.29 °C
241
242
243 1.
244 11.
245 111. Soil Conductivity (EC)
246
247 Obtain soluble salt concentration in soil or soluble ion concentration in liquid fertilizer or planting medium,. The value range of the register is 0 - 20000(Decimal)( Can be greater than 20000).
248
249 For example, if the data you get from the register is 0x00 0xC8, the soil conductivity is 00C8(H) = 200(D) = 200 uS/cm.
250
251
252 Generally, the EC value of irrigation water is less than 800uS / cm.
253

255 11.
256 111. MOD
257
258 Firmware version at least v2.1 supports changing mode.

260 For example, bytes[10]=90
261
262 mod=(bytes[10]>>7)&0x01=1.
263
264
265 Downlink Command:

286 1.
287 11. Uplink Interval
288
289 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:
290
291 [[http:~~/~~/wiki.dragino.com/index.php?title=End_Device_AT_Commands_and_Downlink_Commands#Change_Uplink_Interval>>url:http://wiki.dragino.com/index.php?title=End_Device_AT_Commands_and_Downlink_Commands#Change_Uplink_Interval]]
292
293 1.
294 11. ​Downlink Payload
295
296 By default, LSE50 prints the downlink payload to console port.
297
298 |**Downlink Control Type**|**FPort**|**Type Code**|**Downlink payload size(bytes)**
299 |TDC (Transmit Time Interval)|Any|01|4

304
305 **Examples**
306
307
308 **Set TDC**
309
310 If the payload=0100003C, it means set the END Node’s TDC to 0x00003C=60(S), while type code is 01.
311
312 Payload:    01 00 00 1E    TDC=30S
313
314 Payload:    01 00 00 3C    TDC=60S
315
316
317 **Reset**
318
319 If payload = 0x04FF, it will reset the LSE01

327 11. ​Show Data in DataCake IoT Server
328
329 [[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:
330
331
332 **Step 1**: Be sure that your device is programmed and properly connected to the network at this time.
333
334 **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:
335

343
344
345
346 Step 3: Create an account or log in Datacake.

705
706 The LSE01 battery is a combination of a 4000mAh Li/SOCI2 Battery and a Super Capacitor. The battery is non-rechargeable battery type with a low discharge rate (<2% per year). This type of battery is commonly used in IoT devices such as water meter.
707
708
709 The battery is designed to last for more than 5 years for the LSN50.

728 111. ​Battery Note
729
730 The Li-SICO battery is designed for small current / long period application. It is not good to use a high current, short period transmit method. The recommended minimum period for use of this battery is 5 minutes. If you use a shorter period time to transmit LoRa, then the battery life may be decreased.

735 111. ​Replace the battery
736
737 If Battery is lower than 2.7v, user should replace the battery of LSE01.
738
739
740 You can change the battery in the LSE01.The type of battery is not limited as long as the output is between 3v to 3.6v. On the main board, there is a diode (D1) between the battery and the main circuit. If you need to use a battery with less than 3.3v, please remove the D1 and shortcut the two pads of it so there won’t be voltage drop between battery and main board.
741
742
743 The default battery pack of LSE01 includes a ER18505 plus super capacitor. If user can’t find this pack locally, they can find ER18505 or equivalence, which will also work in most case. The SPC can enlarge the battery life for high frequency use (update period below 5 minutes)

889 How to set up LSE01 to work in 8 channel mode By default, the frequency bands US915, AU915, CN470 work in 72 frequencies. Many gateways are 8 channel gateways, and in this case, the OTAA join time and uplink schedule is long and unpredictable while the end node is hopping in 72 frequencies.
890
891
892 You can configure the end node to work in 8 channel mode by using the AT+CHE command. The 500kHz channels are always included for OTAA.
893
894
895 For example, in **US915** band, the frequency table is as below. By default, the end node will use all channels (0~~71) for OTAA Join process. After the OTAA Join, the end node will use these all channels (0~~71) to send uplink packets.
896
897 [[image:image-20220606154726-3.png]]
898
899 When you use the TTN network, the US915 frequency bands use are:
900
901 * 903.9 - SF7BW125 to SF10BW125
902 * 904.1 - SF7BW125 to SF10BW125
903 * 904.3 - SF7BW125 to SF10BW125
904 * 904.5 - SF7BW125 to SF10BW125
905 * 904.7 - SF7BW125 to SF10BW125
906 * 904.9 - SF7BW125 to SF10BW125
907 * 905.1 - SF7BW125 to SF10BW125
908 * 905.3 - SF7BW125 to SF10BW125
909 * 904.6 - SF8BW500
910
911 Because the end node is now hopping in 72 frequency, it makes it difficult for the devices to Join the TTN network and uplink data. To solve this issue, you can access the device via the AT commands and run:
912
913 (% class="box infomessage" %)
914 (((
915 **AT+CHE=2**
916 )))
917
918 (% class="box infomessage" %)
919 (((
920 **ATZ**
921 )))
922
923 to set the end node to work in 8 channel mode. The device will work in Channel 8-15 & 64-71 for OTAA, and channel 8-15 for Uplink.
924
925
926 The **AU915** band is similar. Below are the AU915 Uplink Channels.

933
934 == 5.1 ​Why I can’t join TTN in US915 / AU915 bands? ==
