Overview of this book

Develop the skills essential for building Internet of Things solutions with this indispensable guide. In an era where industries heavily rely on IoT, this book will quickly familiarize you with its foundations, widespread use, implementation guided by best practices, and the crucial technologies that allow it to work effectively. Starting with the use of IoT in real-life scenarios, this book offers comprehensive insights into basic IoT hardware, protocols, and technologies. You’ll then learn about architecting and implementing solutions such as wireless sensor networks, cloud computing with AWS, and crucial security considerations. You’ll understand how these systems are operated and monitored over time and work with simple to complex, industry-grade systems, adhering to best practices. In later chapters, you’ll be apprised of future IoT trends and strategies to manage the risks and opportunities that come with them. You’ll also get to grips with a diverse set of tools, including hardware such as ESP32 and Raspberry Pi, and software such as Mosquitto and ChatGPT for generative AI capabilities. By the end of this IoT book, you’ll be able to independently build and design complex, industry-standard solutions fully aligned with best practices.

Technical requirements

This chapter will require you to have the following hardware and software installed:

  • Hardware:
    • Two laptops (if you don’t have two, you can use the Raspberry Pi as one of them)
  • Software:
    • Mosquitto client
    • Arduino IDE
    • Command Prompt (you already have this on Windows)
    • cURL

If you are not familiar with Mosquitto or cuRL and/or currently do not have them installed, we will guide you through installation in the following subsections. Otherwise, feel free to skip the next subsections and go to the next heading.

Installing Mosquitto

Mosquitto is an MQTT-based, open source message broker service that sends and receives messages. It is used within remote locations to power connections where the network bandwidth is limited or only a small code footprint is required. It is lightweight and can be used over all types of devices, from low-power microcomputers to full servers. In this chapter, we will be using it to establish MQTT connections. We will...
