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.

Practical – Creating a Telegram household motion detector

In this practical, we will look into creating a Telegram bot that can pass us information regarding motion that has been detected based on a motion detector. This is a great practical to understand how to work with different APIs and how they can interoperate with one another to ensure that we can create an autonomous workload based on different components. These components are what make up the concept of smart homes and large IoT ecosystems that have them interacting with one another, and you can see these components in the Technical requirements section.

Creating a chatbot

To receive messages sent from the ESP32 based on the motion caught by the motion sensor, we have to first create a chatbot on the Telegram app:

  1. To start off, we need to download the Telegram app. We can go to Google Play or the App Store and download and install Telegram from there:
