Using IoT for Classroom Air Quality Monitoring Introduction Indoor air quality (IAQ) plays a critical role in students’ health, concentration, and academic performance. Classrooms, often densely packed and poorly ventilated, can accumulate pollutants like CO₂, dust, and volatile organic compounds (VOCs). With the advancement of the Internet of Things (IoT), real-time monitoring of IAQ is now practical, affordable, and scalable. Why Air Quality Monitoring Matters in Classrooms Poor air quality can cause fatigue, headaches, allergies, and long-term health issues. Studies have shown that high CO₂ levels correlate with reduced cognitive function and decision-making abilities. In developing countries, many classrooms lack basic ventilation standards, making it even more urgent to implement real-time monitoring solutions. System Overview Our IoT-based air quality monitoring system focuses on creating a smart, connected classroom environment. The system consists of: Sensors : CO₂ ...
