24
25 (((
26
27
28 Dragino NSE01 is an **NB-IOT soil moisture & EC sensor** for agricultural IoT. Used to measure the soil moisture of saline-alkali soil and loam. The soil sensor uses the FDR method to calculate soil moisture and compensates it with soil temperature and electrical conductivity. It has also been calibrated for mineral soil types at the factory.
29
30 It can detect **Soil Moisture, Soil Temperature and Soil Conductivity**, and upload its value to the server wirelessly.
31
32 The wireless technology used in NSE01 allows the device to send data at a low data rate and reach ultra-long distances, providing ultra-long-distance spread spectrum Communication.
33
34 NSE01 are powered by **8500mAh Li-SOCI2** batteries, which can be used for up to 5 years.

84 == 2.1 How it works ==
85
86 (((
87 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
88 )))
89
90 (((
91 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 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
97
98 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.
99
100
101 [[image:1654503992078-669.png]]
102
103
104 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.
105
106
107 (% style="color:blue" %)**Step 1**(%%):  Create a device in TTN with the OTAA keys from LSE01.
108
109 Each LSE01 is shipped with a sticker with the default device EUI as below:
110

131 Put a Jumper on JP2 to power on the device. ( The Jumper must be in FLASH position).

134
135
136 (% style="color:blue" %)**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.
