ESP32 Microcontroller and DataBase Applications

Abstract

This diploma thesis deals with the design and implementation of a real-time environmental monitoring system based on the ESP32 microcontroller, incorporating sensors for temperature, humidity, and pressure measurement. The main aim of the project is to integrate the ESP32 module with various cloud database platforms—specifically MySQL with PHP, InfluxDB, ThingSpeak, Blynk DB, Beebotte, and Firebase—to evaluate their capabilities in terms of ease of integration, scalability, data visualization, and suitability for IoT applications. Additionally, a custom web application is developed to provide secure access and real-time visualization of sensor data. The thesis thoroughly documents the technical approach, hardware selection, programming methodologies, and cloud integration processes, offering practical insights into building scalable and reliable IoT monitoring solutions.
