What is IOT?
Internet of Things (IoT) Central in Microsoft Azure is a managed IoT application platform that enables users to build, manage, and operate IoT solutions with ease. It provides a comprehensive and scalable environment for connecting, monitoring, and managing IoT devices, simplifying the deployment and management of IoT applications.
What is Raspberry PI Simulator?
Raspberry Pi Simulator is a powerful tool for prototyping, testing, and learning about Raspberry Pi projects and IoT applications, providing a virtual platform that mimics the functionality of a physical Raspberry Pi.
However, it allows users to simulate a Raspberry Pi with various sensors, interact with Azure services, and build IoT applications in a virtual environment.
Here’s a step-by-step guide on how to do this.
Step:1: Log on to Microsoft Azure account and search for IOT Hub

Step:2: Click on the Create Icon

Step:3: Fill the necessary details such as; Resource group, IOT hub name, Region, Tier, Daily message limit

Step:4: Click Review+Create

Step:5: Click Create

Step:6: Wait for deployment to be completed

Step:7: Go to resource after deployment is completed

Step:8: You must create a device for it. Click on devices icon.

Step:9: Click on Add device

Step:10: Create (Device name, select “Symmetric key” and Enable) and save.

Step:11: Click on the device created

Step: 12: Copy “Primary connection string” and make sure Enable connection to IOT Hub is Enabled

Step:13: Initiate https://azure-samples.github.io/raspberry-pi-web-simulator/ on a web browser , insert or paste the “primary connection string “ from the IOT device portal on Azure into “Line 15” on the Raspberry PI Simulator and click on RUN

Step:14: Raspberry starts blinking Red hence, communicating to the IOT Device in Microsoft Azure portal and recording data or messages as seen below.

Step:15: Go back to IOT Hub overview to show the messages received
