Book Description
ESP32, a low-cost MCU with integrated Wi-Fi and BLE capabilities, has a variety of modules and development boards for building IoT applications effectively. Wi-Fi and BLE are common network stacks in Internet of Things applications that provide cost-effective solutions for your business and project needs.
This book is a fundamental guide for developing ESP32 programs, and begins by explaining GPIO (General Purpose I/O) programming with sensor devices. You'll get up to speed with ESP32 development through a number of IoT projects such as weather stations, sensor loggers, smart homes, Wi-Fi cams, and Wi-Fi wardriving. As you progress, you'll learn how to use ESP32 boards to facilitate interactions between mobile applications and cloud servers, such as AWS.
By the end of this book, you'll have learned how to run a range of IoT projects using the ESP32 chip.
What you will learn
- Understand how to build a sensor monitoring logger
- Build a weather station to sense temperature and humidity using ESP32
- Build your own Wi-Fi wardriving hardware with ESP32
