Abstract


This research advocates an IoT-enabled system for monitoring and purifying air quality, which endeavors to furnish instantaneous updates regarding air quality and facilitate automated air filtration. The proposed system encompasses an air quality sensor that gauges diverse pollutants, including CO2, NO2, and particulate matter. The data collected by the sensor is forwarded to a cloud server through an IoT gateway, which undertakes further examination and manipulation. The system also includes an air purification unit that is activated when the air quality is poor. The purification unit uses various techniques such as HEPA filtration, UV sterilization, and activated carbon absorption to purify the air. The proposed system can be remotely monitored through an LCD display on the model, which provides real-time air quality updates. The system's effectiveness is evaluated through experiments conducted in various indoor and outdoor environments. The results demonstrate that the proposed system can effectively monitor air quality and purify the air to improve indoor and outdoor air quality.
