Design and Implementation of Environmental Monitoring Applications For University Classrooms: Challenges, Methodologies, and Tools

Indoor air quality (IAQ) in educational environments, particularly university classrooms, is a critical factor influencing academic performance and student health. This study explores the design and implementation of environmental monitoring systems in university classrooms, focusing on the technical and methodological challenges involved while analyzing their impact on IAQ and educational variables such as concentration and learning. A systematic literature review identifies vital challenges, methodologies, and tools employed in these systems and their influence on air quality. The findings emphasize the relationship between environmental factors—classroom occupancy, ventilation, and external climatic conditions—and indoor air quality. Complementing this, a preliminary case study was conducted using a prototype system to monitor temperature, humidity, CO\textsubscript{2} levels, particulate matter, luminosity, and volatile organic compounds. The results highlight the potential of environmental monitoring systems to provide actionable insights for improving IAQ, mitigating health risks, and fostering healthier, more productive learning environments. Future research should expand on these findings by investigating the long-term impact of IAQ on academic performance and refining tools for more accurate and reliable environmental monitoring.
