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.

Interfacing sensors and actuators with ESP32

In this section, we’ll dive into the hardware components of our home monitoring and control project. Here, we will explore the seamless integration of a wide range of sensors and actuators with the ESP32 microcontroller, allowing us to transform our ordinary home into a smart and efficiently managed living space.

Our project hinges on the precise coordination of various elements to log data and monitor different rooms in our home, offering us valuable insights and control. To achieve this, we will connect the ESP32 microcontroller to a set of essential components, including DHT22 sensors, motion sensors, Light Dependent Resistor (LDR) modules, and an additional servo motor for the living room.

Each room in our home as depicted in Figure 8.1, will be equipped with a set of sensors. The DHT11 sensors will provide temperature and humidity data, the motion sensors will detect human presence, and the LDR modules will measure light...
