With a variety of widgets, including charts, maps, and tables, dashboards help users gain insights, track trends, and manage IoT deployments efficiently.
	569	+
	570	+
	571	+This section guides you on how to create a dashboard to display temperature and humidity data from the device on a time-series chart. You may also use other widgets in ThingsBoard to display data according to your requirements.
	572	+
	573	+
	574	+In **ThingsBoard**, from the left navigation menu, click **Dashboards**. Then, click the **+** button and select **Create new dashboard** from the dropdown menu.

	598	+
	599	+
	600	+
	601	+In the **Charts: select widget** window, click **Time series chart**.
	602	+
	603	+
	604	+[[image:dashboard-5.png||height="525" width="700"]]
	605	+
	606	+
	607	+Configure the **Time series chart** widget as follows:
	608	+
	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.
	627	+
	628	+
	629	+{{code language="none"}}
	630	+mosquitto_pub -d -q 1 -h 011731f7928xxxxx.s1.eu.hivemq.cloud -p 8883 -t "tb/mqtt-integration-tutorial/sensors/S31B-NB/telemetry" -u "xxxxx" -P "xxxxx" -m '{"temperature":20, "humidity":70}'
	631	+
	632	+mosquitto_pub -d -q 1 -h 011731f7928xxxxx.s1.eu.hivemq.cloud -p 8883 -t "tb/mqtt-integration-tutorial/sensors/S31B-NB/telemetry" -u "xxxxx" -P "xxxxx" -m '{"temperature":22, "humidity":71}'
	633	+
	634	+mosquitto_pub -d -q 1 -h 011731f7928xxxxx.s1.eu.hivemq.cloud -p 8883 -t "tb/mqtt-integration-tutorial/sensors/S31B-NB/telemetry" -u "xxxxx" -P "xxxxx" -m '{"temperature":18, "humidity":79}'
	635	+
	636	+{{/code}}
	637	+
	638	+The chart will update with the values in realtime, as shown in the below image.

	642	+
	643	+
	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.
