Developing IoT Projects with ESP32: Automate your home or business with inexpensive Wi-Fi devices

Master the technique of using ESP32 as an edge device in any IoT application where wireless communication can make life easier

Key Features

• Gain practical experience in working with ESP32
• Learn to interface various electronic devices such as sensors, integrated circuits (ICs), and displays
• Apply your knowledge to build real-world automation projects

Book Description

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 you will learn

• Explore advanced use cases like UART communication, sound and camera features, low-energy scenarios, and scheduling with an RTOS
• Add different types of displays in your projects where immediate output to users is required
• Connect to Wi-Fi and Bluetooth for local network communication
• Connect cloud platforms through different IoT messaging protocols
• Integrate ESP32 with third-party services such as voice assistants and IFTTT
• Discover best practices for implementing IoT security features in a production-grade solution
