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.

Chapter 4: A Deep Dive into the Advanced Features

ESP32 is a full-fledged hardware platform for Internet of Things (IoT) projects. We started our journey with basic features and peripherals to integrate with elementary sensors and actuators. This was just the tip of the iceberg. In this chapter, we are going to use more of its peripherals to experiment with advanced devices such as a speaker and a camera.

Battery-powered products require the use of the energy-saving features of ESP32. We can put ESP32 in sleep mode so that the battery has a longer lifespan. For the purpose of computation even if it is in sleep mode, an Ultra-Low-Power (ULP) coprocessor is integrated into ESP32. The ULP coprocessor has access to some peripherals for sensor integration so that the device can still function while the main processors are in sleep mode. This chapter is the right place to check out if you need your ESP32 device to be battery-powered in your project.

In this chapter, we will cover...
