ABSTRACT
Air pollution is a pressing environmental challenge with significant implications for public health and ecosystems. This research presents a cost-effective and portable air quality monitoring system utilizing an Arduino Uno and an MQ-135 gas sensor. The system is designed to detect and measure the concentration of harmful gases, including CO2, NH3, benzene, and smoke, in real-time. Data is displayed on an I2C-compatible LCD or OLED screen, offering immediate insights into air quality levels. When pollution levels exceed a predefined threshold, the system activates an alert mechanism using a buzzer to indicate hazardous conditions. The proposed system is versatile and can be deployed in various settings, including homes, schools, and offices, providing a practical solution for environmental monitoring. Future enhancements include the integration of wireless communication modules such as ESP8266 to enable remote monitoring through mobile applications or web platforms. This project underscores the importance of air quality awareness and offers a scalable, user-friendly tool for promoting environmental sustainability and healthier living standards.
