Multi-Parameter High Frequency Indoor Microclimate Data from University Classrooms

This dataset provides a comprehensive record of indoor microclimatic conditions measured in university classrooms over a continuous one-year period, with data sampled every ten minutes. The monitoring campaign was conducted in three rooms at the University of Urbino (Italy) to capture variations in indoor environmental quality associated with occupancy patterns, ventilation practices, and seasonal conditions. The dataset includes simultaneous measurements of carbon dioxide concentration, air temperature, relative humidity, particulate matter, and noise level. Each sensor node was installed in a room and connected to a central data acquisition server for storage and visualization. The resulting time series consists of over 80,000 observations per room, enabling fine-grained analysis of temporal dynamics in classroom environments. Data are stored in comma-separated values format, organized by room, and accompanied by metadata describing sensor specifications.
