Abstract: Indoor air pollution poses a significant threat to human health and comfort, with pollutants such as dust, chemicals, and allergens contributing to respiratory problems and discomfort in indoor spaces. To address this issue, we propose a solar-powered smart air monitoring and purification system. Integrated with sensors for temperature, humidity, and air quality measurement, the system detects pollutants in indoor environments in real-time. Utilizing an ESP8266 Wi-Fi module, the system transmits data to the cloud for analysis and monitoring. When air quality surpasses predefined thresholds, the system activates a fan to improve ventilation and incorporates a HEPA filter for enhanced air purification. This proactive approach to indoor air quality management ensures healthier and more comfortable indoor environments for occupants.

Keywords: Indoor air pollution, solar-powered, cloud analysis, HEPA filter.
