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 )))

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.

88
89 (((
90 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
91 )))
92
93 (((
94 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"]].

99 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
100
101 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.
102
103
104 [[image:1654503992078-669.png]]
105
106
107 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.
108
109
110 **Step 1**: Create a device in TTN with the OTAA keys from LSE01.
111
112 Each LSE01 is shipped with a sticker with the default device EUI as below:
113
114 [[image:image-20220606163732-6.jpeg]]
115
116 You can enter this key in the LoRaWAN Server portal. Below is TTN screen shot:

126
127 [[image:1654504683289-357.png]]
128
129
130
131 **Step 2**: Power on LSE01
132
133
134 Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).
135
136 [[image:image-20220606163915-7.png]]
137
138
139 **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.
