IoT-Based Smart Air Quality Monitoring System

In this project, an ESP8266 microcontroller and environmental sensors are used to develop an Internet of Things-enabled system that continuously monitors air quality. The device continually transmits the data to Firebase for remote access after detecting pollutants including PM2.5, CO2, temperature, and humidity. Through a web dashboard or mobile app, users can examine real-time air quality metrics and get notifications when pollution levels surpass predetermined thresholds. Accurate environmental condition tracking is made possible by the ESP8266, which provides effective communication between sensors and Firebase. Urban locations where pollution levels affect people's health and well-being will find this project extremely beneficial. The system is appropriate for homes, workplaces, and public areas since it gives users access to real-time air quality data, enabling them to take prompt action to enhance indoor as well as outdoor environments.
