Overview and Benefits of Azure Internet of Things (IoT) Hub


The IoT is one of the most potent and persistent technological trends in business and shows no signs of slowing under MQTT. Many more business enterprises are planning to apply the technology to their operations shortly under MQTT.

The IoT hub is a service Microsoft Azure provides to connect, provision, and manage millions of IoT devices, communicating large amounts of data per month under the Azure IoT hub.

The IoT hub acts as a bridge between devices and their solutions in the cloud, allowing them to store, analyze and act on data in real time under the Azure IoT hub.


Integrating the detailed Azure IoT Hub to akenza is entirely digital and can be finalized in a few clicks on the Data Flow level; the user can interact and secure transmission between any Low Voltage sensor and the Azure IoT Hub.

Facts about IoT hub:

  • Azure IoT hub offers a managed Internet of Things service in the cloud. It enables a two-way connection between IoT applications and the MQTT tools it includes.
  • The Azure IoT hub umbrella presents organizations with immediate and practical opportunities to cut costs, boost revenue, and improve their operations.
  • Accessing data from your gadgets and delivering instructions and rules back to the MQTT tools are possible with this cloud-to-device communication.
  • Because it also offers the infrastructure to verify, connect, and administer the tools related to it, the Azure IoT hub sets itself apart from competing alternatives.
  • Full-featured and quantifiable IoT solutions are possible with Azure IoT Hub. Any device may upgrade to millions of devices using MQTT and connect to Azure IoT Hub.

Using IoT Hub, manage tools.

The demands placed on IoT operators vary considerably according to the type of operations, including transportation, manufacturing, agricultural, and MQTT services. In addition, there is a complete substitute for IoT operators’ tools.

The Azure IoT hub’s IoT Hub can offer developers the infrastructure, design patterns, and code media center needed to create management solutions for various devices.

Steps to create an IoT hub:

You can create an IoT hub by following the steps given below:

  • Sign in to your Microsoft Azure account.
  • Select New – IoT – IoT hub


Name: Select a name for your IoT hub. If the name is valid, a green check mark will appear. After you click on IoT hub, an IoT hub window will open.

Note: The IoT hub is publically discoverable as a DNS endpoint, so avoid sensitive information while naming it.

Pricing and scale tier: Select an appropriate option according to the need of your application and based on your budget under MQTT. The prices and capacities are shown in a new pane once you click on this option under the Azure IoT hub.

Here, we have chosen the F1-Free Tier IoT Hub.

Note: Only 1 F1-Free Tier IoT Hub is available per account. So please don’t delete the free IoT Hub once you have created it. You won’t be able to select an F1-Free Tier IoT Hub again.

Resource Group: Create a resource group to host the IoT Hub. You can also use an existing resource group if you have created one earlier under the Azure IoT hub.

Location: Select the location closest to you.

You need to scroll down to see this option in the pane. We have selected Central India.

You can pin this IoT Hub to the dashboard by checking the Pin to dashboard option. Click on create the IoT Hub. 

You will get a notification on the completion of the creation of the IoT Hub under the Azure IoT hub. It may take a few minutes to complete the IoT Hub.

Registering a Device in the IoT Hub for your Device

Follow the steps given below to register a device in your IoT Hub:

  1. Open your IoT Hub and click on Device Explorer.
  2. In the Device Explorer pane, click on Add to add a widget to the hub.
  3. In the Add Device pane that opens, fill in the following information:


Device ID: Enter Id for the Device. Device Ids need to be unique. A green check mark will appear if it is a valid device Id. Device Ids are case-sensitive under MQTT.

Note: The device Id may be visible in the logs collected for customer support and troubleshooting, so make sure to avoid sensitive information while naming the Device under the Azure IoT hub.

Authentication Type: Select the symmetric key.

Auto Generate Keys: Select this check box.

Connect Device to IoT Hub: Click Enable.

  • Click on save.
  • Once the Device is created, it will be listed in the Device Explorer option from where we added it. Click on the name of the Device. It will open the Device Details pane.
  • Note down the primary key and the connection string-primary key of the Device. You will require these strings later while developing applications under MQTT. You can copy these strings and note them down in some file or access them later, as explained above under the Azure IoT hub.
