Azure IoT Central Tutorial

Introduction

Azure IoT Central is a fully managed global IoT (Internet of Things) SaaS (Software as a Service) solution that makes it easy to connect, monitor, and manage your IoT assets at scale. This tutorial will guide you through the steps to get started with Azure IoT Central, from creating an application to monitoring your devices.

Step 1: Create an Azure IoT Central Application

To create an Azure IoT Central application, follow these steps:

1. Sign in to the Azure IoT Central portal.
2. Click on "Create a new application".
3. Select a template that fits your industry or use case or start from scratch.
4. Fill in the required details such as application name, URL, and pricing plan.
5. Click "Create" to create your new IoT Central application.

Step 2: Add Devices to Your Application

Once your application is created, you can add devices to it. Here’s how:

1. Navigate to the "Devices" section in your IoT Central application.
2. Click on "New Device".
3. Enter details for your device, such as Device Name and Device ID.
4. Click "Create" to add the device to your application.

After creating the device, IoT Central will generate a connection string that you can use to connect your physical device to the IoT Central application.

Step 3: Simulate Device Telemetry

If you don't have a physical device, you can simulate telemetry data. Follow these steps:

1. Go to the "Devices" section and select the device you created.
2. Navigate to the "Simulated" tab under the device details.
3. Choose the telemetry data you want to simulate and click "Start Simulation".

Step 4: Monitor Device Telemetry

To monitor the telemetry data from your devices:

1. Go to the "Telemetry" section of your IoT Central application.
2. Select the device you want to monitor.
3. View the telemetry data in real-time as it is sent from your device.

Temperature: 22.5°C
Humidity: 60%

Step 5: Create Rules and Actions

You can create rules to trigger actions based on telemetry data. Here's how:

1. Navigate to the "Rules" section in your IoT Central application.
2. Click "New Rule".
3. Define the conditions that will trigger the rule, such as a temperature threshold.
4. Specify the actions to take when the rule is triggered, such as sending an email or invoking an Azure function.
5. Click "Save" to create the rule.

Step 6: Customize Device Templates

Device templates define the capabilities of your devices. To customize a device template:

1. Navigate to the "Device Templates" section in your IoT Central application.
2. Select an existing template or create a new one.
3. Define the telemetry, properties, and commands for the device template.
4. Save the template to apply it to your devices.

Conclusion

In this tutorial, you learned how to create and manage an Azure IoT Central application. You created devices, simulated telemetry, monitored data, and set up rules and actions. Azure IoT Central simplifies the management of IoT devices and helps you scale your IoT solutions efficiently.
