Development of an IoT-Integrated Automated Air Exchanger for Indoor Air Management in Computer Laboratories

The study develops an IoT-integrated automated air exchange system, addressing the issue on poor IAQ within computer laboratories. The developed system addresses gaps in previous solutions by introducing IoT integration and automated interventions to improve IAQ management within computer laboratories. This system is equipped with sensors capable of real-time monitoring of key indoor pollutants, such as carbon dioxide, particulate matter 2.5, and volatile organic compounds. Also, it comprises of an air exchange mechanism that automatically triggers when the pollutants' thresholds exceeded, ensuring timely and efficient way of reducing pollutants to maintain the optimal level of environment conditions. The air exchange mechanism comprises two fans, one for air intake and the other for air exhaustion to provide proper air circulation. Upon simulating real-world conditions in a prototype room model, results show that the system is effective in reducing pollutants' concentrations by measuring the levels of air parameters before and after operation of the system. With IoT-driven and automated intervention capabilities, the system's adaptable design and scalability provide a promising solution for improving the air quality of high-occupancy indoor spaces, allowing for a foundation to support broader real-world applications in industrial settings.
