The ESP32 is a low-cost, low-power, SoC (system on a chip) series of microcontrollers with integrated WiFi and dual-mode Bluetooth. It has shipped >100M units as of 2018 and powers many WiFi devices on the market. This book provides end-to-end coverage of building an IoT system from the ground up to secure data communication techniques from sensors to cloud platforms that will help you to develop production-grade IoT solutions by using the ESP32 SoC.Starting with the fundamentals of IoT supported with real-world use cases, this book will take you through every aspect of building an IoT device using ESP32 from scratch. With every chapter, youâ€™ll learn to expand your IoT applications with features such as sensor communication, integrating popular IoT libraries such as Little FS, LVGL and more, connectivity via. WiFi/BLE, security features, cloud connectivity and real-time data visualization techniques using Grafana. Moving further, an entire section is dedicated to covering AI/ML for embedded systems. You’ll learn to build and run ML applications using TInyML and ESP32-S3 to create state-of-the-art embedded products.The book takes a hands-on approach to have you start building IoT solutions right from the start. An end-to-end IoT solution in the form of a Smart Home is dedicated towards the end of the book where you apply all the techniques learned through the book in real-time.Get started with building secure, production grade IoT systems on ESP32, today!
