Monitoring air quality is essential to monitor public health and the environment. Pollution exists in several forms; nearly each natural thing is currently suffering from the term pollution. Nowadays, everyone has changed their lifestyle, and it results in alarming levels of air pollution. The work presents the real-time air quality monitoring system that measures different environmental parameters and provides real-time data via mobile and desktop platforms. Using Arduino, ESP8266 NodeMCU, and various sensors, the system captures air quality metrics and integrates with Arduino Cloud and the Blynk app to capture the real-time data. The system monitors air quality in real-time and triggers alerts when pollution levels exceed certain defined thresholds. The system is designed to be efficient, scalable, and adaptable, making it suitable for a wide range of applications in urban and industrial environments.
