Many classroom environments lack effective air quality monitoring systems, especially in enclosed spaces with air conditioning, leading to prolonged exposure of students and teachers to poor air quality without timely detection. Even if there are air pollution sources present, the absence of effective alert mechanisms prevents the timely identification and response to air quality issues. Therefore, it is crucial to address the inadequacies in air quality monitoring, the lack of alert mechanisms, and the need for environmental improvements to enhance the overall quality of the learning environment and safeguard the health and learning outcomes of students and teachers.
