The PollyX Device Heatmap indicator visualises air quality data detected by PollyX IoT sensors installed at monitoring sites on the 3Bee Oasi platform. The PollyX device integrates the Sensirion SPS30 particulate matter sensor, based on laser optical diffusion technology, measuring PM2.5 (fine particulate, diameter < 2.5 μm) and PM10 (inhalable particulate, diameter < 10 μm) concentrations.
Data are transmitted in real-time and aggregated weekly by the platform. The spatial heatmap shows particulate concentration distribution across the site area, with geographic coordinates (latitude, longitude) of each PollyX sensor and its average value for the selected period.
This layer is non-generatable via API: its availability depends solely on the user's adoption of a PollyX device.

Spatial heatmap of air quality data detected by PollyX IoT sensors. Sensor: Sensirion SPS30 (optical diffusion laser). Variables: PM2.5 (diameter < 2.5 μm) and PM10 (diameter < 10 μm). Aggregation: weekly average per device. Visualization: geographical coordinates with period average value. Layer not generable — depends on PollyX plan adoption.
