        abstract = {Air quality degradation has become one of the most pressing environmental concerns worldwide, driven by increasing urban growth, industrial expansion, and rising energy demands. Exposure to polluted air negatively affects public health and contributes to environmental deterioration. Most existing air purification technologies rely heavily on conventional electrical power sources, leading to higher energy consumption and additional environmental burdens. To address these challenges, this study proposes a solar-powered air purification system that combines renewable energy utilization with advanced air-cleaning technology.
The developed system harnesses solar energy through photovoltaic panels, which supply power to the purification unit and charge a battery storage system for continuous operation. An Arduino-based control module manages system functions and optimizes performance based on real-time conditions. Air quality is continuously monitored using gas and particulate matter sensors, allowing the system to automatically regulate airflow through a BLDC motor according to pollution levels.
For effective purification, the design incorporates a multi-stage filtration process consisting of HEPA and activated carbon filters. This arrangement efficiently captures fine particulate matter, harmful gases, volatile organic compounds (VOCs), and unpleasant odors. The system is capable of operating independently of the electrical grid, making it particularly suitable for densely populated urban areas, remote regions, and locations experiencing unstable power availability.
Experimental evaluation demonstrates that the proposed solution achieves effective air purification while maintaining low operating costs and reduced environmental impact. By integrating renewable energy generation with intelligent air quality management, the system offers a practical, sustainable, and economically viable approach to enhancing indoor and outdoor air quality. Furthermore, its modular design enables scalability for a wide range of applications, supporting broader adoption of clean energy technologies in environmental protection initiatives.},
