Book Description

The future of IoT has the potential to be limitless. Wouldn't it be great if you could add this to your known technological stacks. But, where to start? Of course, with the basics.

First, you will learn about the most popular hardware and communication protocol, the Raspberry Pi and MQTT. You will see how to use them together by setting up our very own MQTT Server on the Raspberry Pi and understand how it works. The book gets into the details of MQTT, know more about the clients or devices you will connect to your server. You will discover two very popular IoT development boards among project developers: ESP8266 and the ESP32 Dev Boards. You will also learn how to build interactive dashboards on your Pi and monitor your client devices. You will build the dashboard using another popular software - Node RED. You will be able put your theory into a practical use case by creating 2 full scale projects. That's not all, you will also learn how to host your very own MQTT server on a virtual cloud service. Finally, you will be guided on how to move forward from here, what technologies to learn, some project recommendations to polish or test your knowledge.

By the end of this book, you will know how to build meaningful projects using Raspberry Pi and MQTT and how to create dashboards for your projects on Node RED.

What you will learn

• Configure and use a Raspberry Pi for IoT projects
• Implement MQTT communication protocol for projects
• Learn to set up the NodeMCU and ESP32 boards as MQTT clients
• Control a NodeMCU board through a Node RED dashboard hosted on raspberry Pi
• Get LAMP server, Home Assistant, and MariaDB Database on the Raspberry Pi
• Set up an Online MQTT Broker on a cloud service or enterprise service provider platform
• Build full scale end-to-end prototype projects

Who This Book Is For

This book is idea for students who are interested in IoT and want to build projects using the available developer hardware. Educators who want to introduce a course on IoT into their curriculum, technology enthusiasts, and fresher IoT developers will also benefit from this book and find it a good read. You don't require any knowledge about the two main topics the book covers: Raspberry Pi and MQTT. Having a basic knowledge as to what is IoT (Internet of Things) will be useful but not mandatory.
