514 -
515 -ThingsBoard **Dashboards** provide a powerful way to visualize and monitor real-time and historical data from connected devices. They allow users to create interactive, customizable panels displaying telemetry data, device status, and other key metrics. With a variety of widgets, including charts, maps, and tables, dashboards help users gain insights, track trends, and manage IoT deployments efficiently.
516 -
517 -
518 -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.
519 -
520 -
521 -First simulate a few messages using MQTT. This time, we have added the 'humidity' field to the payload. Eg:

599 -Now, let's experiment with sending data to ThingsBoard using a real NB-IoT device. For example, we will use the **S31B-NB**.
600 -
601 -First, configure the NB-IoT device with the necessary MQTT settings using AT commands. Below is a list of AT commands you can use.
602 -
603 -

606 -* **AT+PRO=3,3    **~/~/ Use MQTT to connect to ThingsBoard. Payload Type set to 3.

608 -* **AT+PUBTOPIC=<MQTT publish topic> Eg: TS01-NB**
609 -* **AT+CLIENT=null**
610 -* **AT+UNAME=<MQTT Username>**
611 -* **AT+PWD=<MQTT Password>**
612 -* **AT+SERVADDR=<Broker address, Port>**
613 -
614 -Test your uplink by pressing the ACT button for 1 second.
615 -
616 -
617 -The following image shows the uplink payload of a real Dragino device. The publish topic is **TS01-NB**, and the device name is **861275077962896**, which is represented by the **IMEI**.

273 +If the integration was performed without errors, after the transmission of the first telemetry, a new device with the name “S31B-NB” will appear in the Devices → All. Also, you can verify the input and output data, respectively, before and after conversion in Data converters → UDP Uplink Converter NB/CB → Events.
