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.

Exploring MQTT for IoT communication with ESP32

Among the many different protocols used in IoT, MQTT stands out as a powerful option. MQTT, with its lightweight and pub-sub messaging paradigm, has found its place as a go-to protocol for enabling efficient communication between resource-constrained devices such as ESP32 and remote servers.

This section takes an in-depth journey into the domain of MQTT communication, purposefully tailored for ESP32 projects. We will explore the mechanisms through which ESP32 can seamlessly engage with MQTT brokers, granting IoT devices the capability to share data, receive updates, and actively participate in the dynamic ecosystem of IoT.

What is MQTT?

MQTT is a lightweight and efficient messaging protocol designed for the efficient exchange of data between devices, especially in scenarios where bandwidth and resources are limited. It was originally developed by IBM in the late 1990s and has since become a widely adopted protocol in the realm...
