Indoor Carbon Dioxide, Temperature and Humidity Dataset from the Brive Campus (2024)

This dataset contains raw indoor environmental measurements from 13 sensor nodes in the MEDYBAT wireless sensor network deployed at the IUT campus in Brive-la-Gaillarde, France. The files contain carbon dioxide (CO₂), temperature and humidity records exported for 2024. The nominal CO₂ reporting interval is 5 minutes for two nodes and 10 minutes for the other 11 nodes. The 11 nodes with a 10-minute interval were used in the study "A Lightweight Node-Level Adaptive Sampling Method for Environmental Monitoring: A Case Study on Air Quality". The raw dataset includes all 13 nodes. The data are provided as one CSV file per node in a 7z archive. See the accompanying README for the file structure, column names and node groups.
