Hello Micheal Sakr,
We haven't heard back from you whether the above suggestions from Sander and Dom helped or not.
In addition to the great resources which shared above, also see below useful information and let us know if you have any further queries.
To learn Azure IoT, you can start with the Azure IoT Fundamentals documentation, which provides an overview of the technologies and services you can use to build an Azure IoT solution.
You can find the more information here: What Azure technologies and services can you use to create IoT solutions?
To find accelerometer sensors that are compatible with Azure, you can start by checking the Azure Certified for IoT device catalog, which lists devices that have been tested and certified to work with Azure IoT services.
You can find the device catalog here: Azure Certified Device catalog
You can also check the Azure IoT device selection guide, which provides guidance on choosing a hardware device for prototyping Azure IoT solutions. You can find the guide here: IoT device selection list
In addition, you can try one of the quickstart for Azure IoT Central, which provides a hands-on experience for building an Azure IoT solution.
I hope this information helps you get started with learning Azure IoT and finding accelerometer sensors that are compatible with Azure. If you have any further questions, feel free to ask.
