The increasing awareness of the adverse health effects of air pollutants has driven the need to monitor indoor air quality status. Indoor sensors are indispensable for IAQ monitoring because they provide continuous and real-time data, ensuring that indoor spaces remain safe and comfortable, especially in commercial and public buildings where large numbers of people are present . Advances in sensor technology have enabled the development of low-cost, highly sensitive devices capable of detecting various air pollutants . Accurate sensor readings are essential for maintaining healthy indoor environments and provide practical guidelines to adjust HVAC systems and their energy use . However, the accuracy of IAQ sensors is highly dependent on their placement within a space, as environmental factors, airflow patterns, and other variables can significantly affect sensor performance. Hence, the strategic positioning of sensors plays a critical role in ensuring accurate and real-time IAQ data collection (4).
