Overview of this book

ESP32 is a versatile microcontroller and a great starting point for anyone venturing into the IoT realm, but its configuration and interfacing of sensors can be challenging for new users. Arduino Integrated Development Environment (IDE) simplifies programming, uploading code, and utilization of ESP32 capabilities, enabling users to incorporate it into their IoT projects with ease. This book will help you learn the essentials of sensing, networking, data processing, and applications with ESP32, laying a strong foundation for further IoT development. Starting with ESP32 and Arduino Ide 2.0 basics, you'll first explore practical implementation examples of interfacing sensors with ESP32. These examples will also teach you how to interface the ESP32 camera and display modules with ESP32. As you progress, you’ll get to grips with IoT network and data protocols, as well as the many options they unlock within IoT applications. The book will also help you leverage your newly acquired knowledge with exciting projects ranging from smart connected devices to data loggers and automation. By the end of this book, you'll confidently navigate ESP32 projects with newfound knowledge and skills, know what IoT protocol to select for your applications, and successfully build and deploy your own IoT projects.

Expanding ESP32 connectivity beyond Wi-Fi and BLE

We have already explored ESP32 Wi-Fi and BLE capabilities. While the built-in Wi-Fi and BLE capabilities of the ESP32 offer robust connectivity options, there are scenarios where these technologies alone may not suffice:

  • Remote and disconnected areas: In remote or rural areas with limited Wi-Fi infrastructure, establishing a reliable internet connection can be challenging. Here, cellular communication comes to the rescue.
  • Long-range communication: While Wi-Fi and BLE are suitable for short-range communication, they may not be ideal for applications requiring long-range connectivity.
  • Contactless and close proximity interaction: In scenarios where physical contact or proximity is not feasible, NFC presents an excellent option.

In each of these scenarios, the ESP32, when combined with additional communication modules, can overcome the limitations of Wi-Fi and BLE and enable connectivity in diverse and challenging...
