DESIGN AND DEVELOPMENT OF AN OUTDOOR AIR PURIFIERFOR DOMESTIC AND TRAFFIC SIGNAL AREAS

Abstract: This project focuses on the design and development of an out door air purifier suitable for domestic surroundings and traffic signal areas, where air pollution levels are significantly high due to vehicular emissions and dust. The system integrates high efficiency particulate air (HEPA)filtration, activated carbon filters, and UV-C sterilization to remove particulate matter (PM2.5 and PM1O0), toxic gases, and microbialogical contaminants. A solar- powered system with a smart air quality monitoring unit (AQI sensor) ensures energy efficiency and real-time performance tracking. The compact and weather-resistant design enables easy installation and maintenance. This innovation aims to reduce localized air pollution, improve public health, and enhance air quality in urban environments. The designed outdoor air purifier successfully addresses the growing problem of air pollution in domestic and traffic signal areas by combining advanced filtration, sterilization, and smart monitoring technologies. Through the integration of HEPA and activated carbon filters along with UV-C sterilization, the system effectively removes harmful pollutants, toxic gases, and microorganisms from the surrounding air. The inclusion of solar power ensures sustainable operation, while the smart AQI monitoring unit provides real-time feedback for efficient performance management. Overall, this project contributes to improving air quality, promoting public health, and offering an eco-friendly, cost-effective solution to combat air pollution in high-risk environments.
