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.

What this book covers

Chapter 1, Getting Started with ESP32, introduces you to IoT technology in general, the ESP32 hardware, and development environment options.

Chapter 2, Talking to the Earth – Sensors and Actuators, discusses different types of sensors and actuators and how to interface them with ESP32.

Chapter 3, Impressive Outputs with Displays, explains how to select and use different display types in ESP32 projects. FreeRTOS is also discussed in detail.

Chapter 4, A Deep Dive into the Advanced Features, covers audio/video applications with ESP32 and the power management subsystem for low-power requirements.

Chapter 5, Practice – Multisensor for Your Room, is the first reference project in the book, where several sensors are integrated as a single ESP32 device.

Chapter 6, Good Old Friend – Wi-Fi, shows how to use ESP32 in the station and access point modes of Wi-Fi. Some TCP/IP protocols are discussed in the context of ESP32.

Chapter 7, Security First!, explores the security features of ESP32 and provides examples of secure firmware updates and secure communication techniques.

Chapter 8, I Can Speak BLE, introduces the BLE basics and shows how to develop a BLE beacon, a GATT server, and BLE mesh nodes.

Chapter 9, Practice – Making Your Home Smart, builds a full-fledged smart home solution with a gateway, a light sensor, and a relay switch in a BLE mesh network.

Chapter 10, No Cloud, No IoT – Cloud Platforms and Services, discusses the important IoT protocols and introduces the IoT platforms from different providers with an example of AWS IoT integration.

Chapter 11, Connectivity Is Never Enough – Third-Party Integrations, focuses on integration with popular services such as voice assistants and IFTTT.

Chapter 12, Practice – A Voice-Controlled Smart Fan, converts an ordinary fan into an Alexa-enabled smart device as the last project of the book.
