Preface

ESP32 is a low-cost MCU with integrated Wi-Fi and BLE. Various modules and development boards-based ESP32 are available to build Internet-of-Things (IoT) applications easily. Wi-Fi and BLE are common network stacks in IoT applications. These network modules can fulfil your business and project needs, providing cost-effective benefits.

This book will serve as a fundamental guide to developing an ESP32 program. We will start with GPIO programming, which will involve some sensor devices. Then, we will get deep into ESP32 development by building some IoT projects such as a weather station, a sensor logger, a smart home device, a Wi-Fi camera, and Wi-Fi Wardriving. Lastly, we will enable ESP32 to interact with mobile applications and cloud servers such as Amazon AWS.

By the end of this book, you will be up and running with various IoT projects based on the ESP32 chip.
