Use Sensors to Intelligence to Build Secure, Scalable IoT Systems Book Description Connected devices are reshaping every industry — from smart manufacturing and precision agriculture to healthcare monitoring and autonomous systems. Kickstart IoT Systems Engineering provides a comprehensive, hands-on path from core IoT concepts to production-grade, AI-enabled deployments, bridging the gap between academic foundations and real industry practice. You begin with IoT architecture, sensors, microcontrollers, and communication protocols — including MQTT, REST APIs, LoRa, and BLE — then progressively build toward cloud-connected systems using Firebase, AWS IoT Core, and enterprise integration patterns. What you will learn ● Program Arduino, NodeMCU, and ESP32 for real-world IoT applications. ● Connect devices to cloud platforms using MQTT, REST APIs, and Firebase. ● Implement encryption, authentication, and hardening for secure IoT systems. Who is This Book For? This book is tailored for students pursuing courses like BE, B.Tech, BCA, MCA, IoT developers, embedded engineers, and AI/ML practitioners who want to build practical, cloud-connected IoT systems. Beginners will also find a strong foundation in core concepts, and professionals will gain hands-on exposure to Edge AI, security, and enterprise-scale deployment.
