The first step to implement this project is to configure AWS IoT. Each IoT device that wants to access AWS IoT should be registered so that we can obtain a certificate and key files. This step is required. Otherwise, you will get an error while your device sends data to AWS IoT.

We have learned how to configure AWS IoT from the previous chapters. In this demo, we need at least one registered IoT device on AWS IoT. After  you have registered, you should have a certificate, public, and private key files. You also need the AWS certificate file. Please read the previous chapters to perform this task. This IoT device is used to send the data to AWS IoT. This scenario can also be called a sensor data publisher. You can see my registered IoT devices in the following screenshot
