15 == 1.1 What is D2x-LB LoRaWAN Temperature Sensor ==
16
17
18 The Dragino D2x-LB is a (% style="color:blue" %)**LoRaWAN Temperature Sensor**(%%) for Internet of Things solution. D2x-LB has 5v and 12v output , 4~~20mA, 0~~30v input interface to power and get value from Analog Sensor. D2x-LB will convert the Analog Value to LoRaWAN wireless data and send to IoT platform via LoRaWAN gateway.
19
20 The LoRa wireless technology used in D2x-LB 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.
21
22 The temperature sensor used in D2x-LB can (% style="color:blue" %)**measure -55°C ~~ 125°C with accuracy ±0.5°C (max ±2.0 °C)**(%%).
23
24 D2x-LB supports (% style="color:blue" %)**temperature alarm feature,**(%%) user can set temperature alarm for instant notice.
25
26 D2x-LB has max 3 probes which measure maximum 3 temperature points.
27
28 D2x-LB (% style="color:blue" %)**supports BLE configure**(%%) and (% style="color:blue" %)**wireless OTA update**(%%) which make user easy to use.
29
30 D2x-LB is powered by (% style="color:blue" %)**8500mAh Li-SOCI2 battery**(%%), it is designed for long term use up to 5 years.
31
32 Each D2x-LB 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.

171
172 == 2.1 How it works ==
173
174
175 The D2x-LB is configured as (% style="color:#037691" %)**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 press the button to activate the D2x-LB. It will automatically join the network via OTAA and start to send the sensor value. The default uplink interval is 20 minutes.
176
177
178 == 2.2 ​Quick guide to connect to LoRaWAN server (OTAA) ==
179
180
181 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 [[LPS8v2>>url:https://www.dragino.com/products/lora-lorawan-gateway/item/228-lps8v2.html]] as a LoRaWAN gateway in this example.
182
183
184 [[image:1675144005218-297.png]]
185
186
187 The LPS8V2 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.
188
189
190 (% style="color:blue" %)**Step 1:**(%%) Create a device in TTN with the OTAA keys from D2x-LB.
191
192 Each D2x-LB is shipped with a sticker with the default device EUI as below:
193
194 [[image:image-20230131134744-2.jpeg]]

220
221 (% style="color:blue" %)**Step 2:**(%%) Activate on D2x-LB
222
223
224 Press the button for 5 seconds to activate the D2x-LB.
225
226 (% style="color:green" %)**Green led**(%%) will fast blink 5 times, device will enter (% style="color:blue" %)**OTA mode**(%%) for 3 seconds. And then start to JOIN LoRaWAN network. (% style="color:green" %)**Green led**(%%) will solidly turn on for 5 seconds after joined in network.
227
228 After join success, it will start to upload messages to TTN and you can see the messages in the panel.
