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

In this chapter, we will continue with the existing toolchain and development environment. However, the examples will require new libraries. The links for all new libraries will be provided in the corresponding sections.

In addition to our existing ESP32 devkit, we will need one more for the Universal Asynchronous Receiver-Transmitter (UART) example where we connect two devkits to communicate with each other.

The camera example is implemented with a special kit, AiThinker ESP32-CAM. We use this devkit because it has an integrated camera sensor port and microSD card slot, so we don't need to worry about pin connections. Moreover, the devkit comes with a camera sensor that can be easily attached to the port.

All other sensors and actuators will be listed in each example so that you can easily follow the Fritzing diagrams.
