Step 1: Introduction
The Internet of Things (IoT) is a network of physical devices that connect to and exchange data with other devices and services over the Internet or other network.
There are currently over ten billion connected devices in the world and more are added every year. Anything that can be embedded with the necessary sensors and software can be connected over the internet.
Azure IoT Hub is a managed service hosted in the cloud that acts as a central message hub for communication between an IoT application and its attached devices. You can connect millions of devices and their backend solutions reliably and securely. Almost any device can be connected to an IoT hub.
You can integrate IoT Hub with other Azure services to build complete, end-to-end solutions. For example, use:
Azure Event Grid to enable your business to react quickly to critical events in a reliable, scalable, and secure manner.
Azure Logic Apps to automate business processes.
Azure Machine Learning to add machine learning and AI models to your solution.
Azure Stream Analytics to run real-time analytic computations on the data streaming from your devices.
Here, we will be Creating a practical IoT solution using Azure IoT Hub involves several steps, including setting up the IoT Hub, registering a device, authenticating a connection to an IoT device using online Raspberry Pi device simulator. and managing data flow between the device and the cloud.
Here’s a step-by-step guide to help you get started:
Step 2: Set Up Azure IoT Hub
Sign in to Azure portal
Step 3: Create an IoT Hub
Go to the Azure portal.
Search for "IoT Hub".
- Click "Create".
Fill in the necessary information such as the subscription, resource group, region, and name for your IoT Hub.
Choose the pricing and scale tier according to your needs.
- Click "Review + create" and then "Create".
Step 4: Register a Device
- Navigate to Your IoT Hub:
- In the Azure portal, navigate to your IoT Hub.
- Add a Device:
In the IoT Hub navigation menu, select "Devices" under the "Explorers" section.
Click on "+ New" to add a new device.
Provide a unique device ID.
Configure additional settings such as authentication type and primary/secondary keys(Optional).
Click "Save".
Step 5: Set Up a Device to Connect to IoT Hub
- Obtain Device Connection String
After creating the device, navigate to it in the IoT Hub Devices section.
Copy the primary connection string. This will be used by your device to connect to the IoT Hub.
- Configure Your Device: Use the primary connection string in the IoT Hub to establish a connection to your device.
- Authentication using Raspberry Pi device simulator Authenticating a connection to an IoT device using online Raspberry Pi device simulator. On line 15 of the Raspberry pi device simulator, replace the string with Primary Connection string
Step 5: Set Up Data Routing
- Create Routes for Data
- In the IoT Hub, go to "Message routing" under "Messaging".
- Select a storage account and container
- Create a message route
- Set up routes to send data to different endpoints like storage accounts, event hubs, or custom endpoints.
- Set up file upload
Step 6: Managing data flow between the device and the cloud
From the Cloud to the Device
In the IoT Hub menu, select "Devices" under the "Explorers" section.
Select the device to which you want to send a message.
Click on "Message to Device".
Enter the message payload.
Click "Send".
Send a message from the IoT Hub to the Raspberry pi simulator.
Send message using Device Twin:
In the IoT Hub menu, select "Devices" under the "Explorers" section.
- Go to your device, click properties and type in the "Editable Property".
-
Click Device in IoT Hub and select "Device Twin" to view the message.
By following these steps, you can create a basic IoT solution using Azure IoT Hub, allowing you to connect devices, send data to the cloud, and monitor the data flow.
