Indoor air quality (IAQ) in educational environments significantly impacts student health and productivity. This research presents an electronic system for monitoring IAQ, focusing on detecting carbon dioxide (CO2) and volatile organic compounds (VOCs) using a microcontroller-based prototype. Inspired by previous research linking poor IAQ with student performance, this system was developed to measure and analyze these parameters for use in educational facilities. The proposed system utilizes commercially available Arduino-based sensors and components, enabling real-time data collection and analysis. Preliminary results indicate that the system detects changes in CO2 and VOC levels in realtime. The system was designed to wirelessly send real-time sensor readings to an online dashboard, which allows for sharing the data to the cloud. The data can be internally shared with the members of an institution to allow for intervention if necessary. This research emphasizes sensor calibration and validation, ensuring the system’s readiness for real-world classroom settings, and offering a practical solution to improve IAQ in educational environments.
