1.INTRODUCTION Air pollution is a major environmental and health concern, especially in urban areas where industrial emissions, vehicle exhaust, and other pollutants degrade air quality. Poor air quality contributes to respiratory diseases, cardiovascular issues, and overall reduced life expectancy. Monitoring and managing air quality effectively is crucial to ensuring a healthier living environment. The Smart Air Quality Management System is designed to provide real-time air quality monitoring and automated control of ventilation systems. Using an ESP32 microcontroller, MQ-05 sensor, and L298N motor driver, the system detects air pollution levels and adjusts fan speed accordingly. The LCD display and Blynk mobile app integration enable users to access air quality data remotely. This intelligent system optimizes energy consumption while maintaining clean air, making it a practical solution for both indoor and outdoor applications. By leveraging IoT and automation, this project contributes to smarter, healthier urban living.
