	609	+* **Datasource** - select S31B-NB device you provisioned.
	610	+* **Series**:
	611	+** **temperature** - you can see this key by default.
	612	+** **humidity** - Click **Add series** button. Then add the **humidity** for the key and then type **%** as its unit.
	613	+* Click on the **Add** button.
	614	+
	615	+[[image:timeseries-1.png||height="491" width="700"]]
	616	+
	617	+
	618	+The time-series chart will appear in edit mode. Resize it by clicking and dragging the lower-right corner.
	619	+
	620	+Click the **Save** button to add the widget to the dashboard.
	621	+
	622	+
	623	+[[image:timeseries-3.png||height="347" width="700"]]
	624	+
	625	+
	626	+Now send the following MQTT messages from the terminal to simulate the data.

	644	+= 7. Configure NB-IoT Sensor =
	645	+
	646	+
	647	+Now, let's experiment with sending data to ThingsBoard using a real NB-IoT device. For example, we will use the **S31B-NB**.
	648	+
	649	+First, configure the NB-IoT device with the necessary MQTT settings using AT commands. Below is a list of AT commands you can use.
	650	+
	651	+
	652	+**AT Commands**
	653	+
	654	+* **AT+PRO=3,3    **~/~/ Use MQTT to connect to ThingsBoard. Payload Type set to 3.
	655	+* **AT+SUBTOPIC=<MQTT topic>**
	656	+* **AT+PUBTOPIC=<MQTT topic>**
	657	+* **AT+CLIENT=null**
	658	+* **AT+UNAME=<MQTT Username>**
	659	+* **AT+PWD=<MQTT Password>**
	660	+* **AT+SERVADDR=<Broker address, Port>**
	661	+
	662	+Test your uplink by pressing the ACT button for 1 second.
