Developing IoT Projects with ESP32

By: Vedat Ozan Oner

Overview of this book

Developing IoT Projects with ESP32 provides end-to-end coverage of secure data communication techniques from sensors to cloud platforms that will help you to develop production-grade IoT solutions by using the ESP32 SoC. You'll learn how to employ ESP32 in your IoT projects by interfacing with different sensors and actuators using different types of serial protocols. This book will show you how some projects require immediate output for end-users, and cover different display technologies as well as examples of driving different types of displays. The book features a dedicated chapter on cybersecurity packed with hands-on examples. As you progress, you'll get to grips with BLE technologies and BLE mesh networking and work on a complete smart home project where all nodes communicate over a BLE mesh. Later chapters will show you how IoT requires cloud connectivity most of the time and remote access to smart devices. You'll also see how cloud platforms and third-party integrations enable endless possibilities for your end-users, such as insights with big data analytics and predictive maintenance to minimize costs. By the end of this book, you'll have developed the skills you need to start using ESP32 in your next wireless IoT project and meet the project's requirements by building effective, efficient, and secure solutions.

Technical requirements

Throughout the book, we're going to use Visual Studio Code (VS Code) as the integrated development environment (IDE). If you don't have it, you can find it here: https://code.visualstudio.com/.

As the ESP32 devkit, I have ESP32-DevKitC V4 from AZ-Delivery. However, the examples will compile and run successfully for most—if not all—of the ESP32 devkits with an ESP32 series chip. You can buy one from the AZ-Delivery website or from online marketplaces such as Amazon or eBay.

I have used many sensors and actuators in the examples. You will see their types and models under the related topics, so you can order them from online marketplaces as well. You will also need a breadboard, jumper wires, and resistors for prototyping.

The source code in the examples is located in the repository found at this link: https://github.com/PacktPublishing/Internet-of-Things-with-ESP32/tree/main/ch2
