Sensor Data monitoring Allergen and Particle Concentration

The PollenSense 2025 dataset contains high-resolution, near-real-time measurements of airborne particle concentrations collected by PollenSense devices across four European countries. The devices operate automatically by drawing in air, capturing images of particles collected on a rotating transparent tape, and using a commercial algorithm to detect and classify the particles. These include pollen, fungal spores, and other organic or inorganic particulates. Key characteristics: Geographical coverage: Georgia, Greece, United Kingdom, Finland Time period: February to October 2025 (varies by country) Measurement Unit: Particle concentration per volume of air. Sampling Frequency: Sampling time for Pollensense (plnsns) is 5 min
