Indoor air quality (IAQ) has significant impacts on human health. High variabilities in indoor pollution levels are often expected due to co-impacts of complex outdoor and sources exchange conditions. By using low-cost sensors, this study aimed examine the differences pollutant concentrations between different environments including a dormitory, an office, laboratory, classroom, dining hall library university campus. Generally, particulate matter (PM) were lower than levels, with overall indoor/outdoor (I/O) ratio predominantly <1. activities (e.g. breathing, exercise, use conditioning or electronic equipment), along environmental factors such as temperature relative humidity, co-affected variation PM significantly. The results showed that low concentration exposure students dinning could benefit from its good ventilation frequent cleaning measures. office contributed more IAQ other locations. Enhanced regular emerged effective strategies for improving IAQ. These findings held important implications comprehending indoor–outdoor dynamics diverse building pollutants campuses their potential population, offering valuable insights enhancing
