Developing IoT Projects with ESP32: Unlock the full Potential of ESP32 in IoT development to create production-grade smart devices

ESP32, the low-cost, energy-efficient system-on-a-chip (SoC) microcontroller, has become a cornerstone of modern Wi-Fi-enabled devices, driving innovation across the Internet of Things (IoT) landscape. This comprehensive guide offers a practical, end-to-end approach to building secure, scalable IoT systems using the powerful ESP32 platform.

From foundational concepts to advanced implementation, the book walks you through the complete lifecycle of developing an IoT device with ESP32. Beginning with essential IoT principles and real-world use cases, each chapter progressively builds your skills—covering sensor communication, integration of key libraries like LittleFS and LVGL, Wi-Fi connectivity, data security, and cloud integration. You'll also learn how to visualize real-time data using tools like Grafana, making your solutions truly production-ready.

A special section is dedicated to artificial intelligence and machine learning (AI/ML) for embedded systems. You'll explore how to build and deploy tinyML models on the ESP32-S3, enabling intelligent edge computing capabilities for your next-generation embedded products.

Adopting a hands-on, project-driven approach, the book ensures that you can apply your knowledge from day one. As a capstone, you'll develop a full-scale Smart Home system, consolidating all the concepts and technologies explored throughout the book.

Whether you're a maker, engineer, or embedded systems developer, this book equips you to build secure, real-world IoT solutions with ESP32—ready for deployment in today’s connected world. More information...
