Abstract: The Solar-Powered Smart Air Purification Sys- tem represents a revolutionary approach to addressing out- door air pollution through autonomous, renewable energy- driven technology. This innovative system combines micro- controller architecture with solar power generation to create a self-sustaining mobile air purification unit capable of de- tecting, analyzing, and treating localized air quality issues in real-time. The system integrates advanced sensor technologies including Light Dependent Resistor (LDR) sensors for partic- ulate matter detection and MQ series gas sensors for compre- hensive air quality monitoring, enabling precise identification of pollution hotspots. Upon detection of suboptimal air con- ditions, the system autonomously activates its HEPA filtration mechanism through relay-controlled switching, providing im- mediate and targeted air purification. The solar-powered de- sign ensures continuous operation during daylight hours while maintaining energy efficiency through intelligent power man- agement. This eco-friendly solution addresses the growing need for localized air quality management in outdoor environ- ments, offering a scalable and sustainable approach to envi- ronmental protection.
