ABSTRACT: -Air pollution poses a severe threat to public health and the environment due to the presence of pollutants such as PM2.5, PM10, NOₓ, CO, and volatile organic compounds (VOCs). Conventional air purification systems are primarily limited to indoor environments and lack scalability for outdoor applications. This paper proposes a solar-powered outdoor air purification system integrated with real-time air quality monitoring. The system operates using renewable solar energy, ensuring sustainable and energy-efficient performance. A multi-stage filtration mechanism, comprising HEPA filters, activated carbon, and photocatalytic oxidation layers, is employed for effective removal of particulate matter and gaseous pollutants. An IoT-enabled sensing module continuously monitors key air quality parameters and computes the Air Quality Index (AQI). The collected data is transmitted to a cloud-based platform for real-time analysis, visualization, and public accessibility. Furthermore, the system incorporates a carbon credit generation framework based on quantified pollutant reduction metrics, enabling potential economic benefits. The proposed solution offers a scalable, cost-effective, and environmentally sustainable approach to improving outdoor air quality and supporting climate action initiatives.
