Abstract

In today’s world, one of the growing concerns is Air Pollution, due to its adverse impact on human health and environmental quality. This research paper presents the design and implementation of a Real-Time Air Quality Monitoring System measuring the Air Quality Index (AQI) using sensors such as MQ135, PM2.5, and DHT11. The ESP8266 microcontroller is used to collect and analyze data. The system is built to provide local display via LCD and remote display through a web dashboard interface. The system has buzzer alerts for local alert generation when AQI thresholds are crossed, and alert messages are generated simultaneously in the web interface. The system uses the HTTP protocol for communication and let the users download CSV files to access the previous air quality data history. The proposed model aims to develop a low-cost, real-time sensing Air Quality Monitor using widely available microcontrollers and sensors to bring awareness to every individual about the harmful living environment.
