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

The chapter projects are located here:

We need developer accounts on AWS. The prerequisites section provides the links to the pages that explain how to create Alexa and AWS developer accounts, here: https://developer.amazon.com/en-US/docs/alexa/smarthome/steps-to-build-a-smart-home-skill.html#prerequisites.

We also need an IFTTT and a Google account for the last example of the chapter where we integrate ESP32 with the IFTTT service.

As hardware, we will use an ESP32 devkit and a DHT11 sensor. It would also be helpful to have an Alexa built-in device, such as Amazon Echo, but it is not mandatory to complete the example.

Using voice assistants

Voice assistants provide another dimension in human-machine interaction. The classical means of interaction is to use a graphical user interface (GUI). In addition to this, a voice assistant introduces a voice user interface...
