AEPM-Net Multi-Testbed IoT Air Quality Dataset

This dataset contains multi-source air quality measurements collected from IoT-based nanosensor nodes deployed across industrial, commercial, institutional, laboratory, and residential environments. The data include key pollutant concentrations (CO, NO, NO₂, SO₂, VOC, PM2.5, PM10) and environmental parameters such as temperature and humidity, recorded at 5-minute intervals over a 90-day monitoring period (June–August 2025). The dataset comprises data from 8 sensor nodes, forming a high-resolution time-series dataset for air quality monitoring and pollution prediction research.
