Hands-On Internet of Things with MQTT

By: Tim Pulver

Overview of this book

MQ Telemetry Transport (MQTT) is a lightweight messaging protocol for smart devices that can be used to build exciting, highly scalable Internet of Things (IoT) projects. This book will get you started with a quick introduction to the concepts of IoT and MQTT and explain how the latter can help you build your own internet-connected prototypes. As you advance, you’ll gain insights into how microcontrollers communicate, and you'll get to grips with the different messaging protocols and techniques involved. Once you are well-versed with the essential concepts, you’ll be able to put what you’ve learned into practice by building three projects from scratch, including an automatic pet food dispenser and a smart e-ink to-do display. You’ll also discover how to present your own prototypes professionally. In addition to this, you'll learn how to use technologies from third-party web service providers, along with other rapid prototyping technologies, such as laser cutting, 3D printing, and PCB production. By the end of this book, you’ll have gained hands-on experience in using MQTT to build your own IoT prototypes.

Summary

In this chapter, you were introduced to a lot of different principles, protocols, and microcontroller boards used in IoT prototyping. We've learned what constitutes the client-server architecture. Next, we looked at how the frontend and backend play together and how machines communicate with one another using APIs. Finally, we learned about the frameworks that use web development technologies such as HTML, CSS, and JavaScript to build desktop and mobile apps, which can communicate with your prototype. We also had a look at various communication methods; devices can transmit information not only over the internet, but also by using radio signals.

One of the most common modules for integrating radio-communication into your project is called XBee, and uses the ZigBee specification. Some devices also ship with Thread support—an upcoming radio-based protocol...
