IoT Data Logging with ESP32 and Databases

Have you ever wanted to take your hardware projects to the next level by saving and displaying sensor readings online? Connecting microcontrollers to remote servers allows you to monitor environments, track assets, and build powerful Internet of Things applications from anywhere. This course guides you through the process of bridging the physical and digital worlds. You will transition from reading basic sensor data on a local board to securely transmitting, storing, and presenting that information on a web-connected database. What you'll learn: - Understand the core concepts of IoT architecture and ESP32 Wi-Fi capabilities - Configure secure HTTPS connections to safely transmit data from your microcontroller - Design and structure database tables to store time-series sensor logs efficiently - Build lightweight REST APIs to receive data payloads from the ESP32 - Implement basic web dashboards to read and display database records in real time - Troubleshoot connection issues and optimize power consumption for remote logging. You will start with the absolute fundamentals of ESP32 hardware and web protocols before moving step-by-step through database setup and server-side integration. This text-based course is designed for hobbyists, makers, and aspiring IoT developers who want to learn the foundations of connected hardware without any prior database experience.
