From the field · Tuscan Maremma, Italy
The buzzes Spectrum counted in the Tuscan Maremma, Italy
39,530 recordings from 5 sensors between June 2026 and September 2026; 3,750 of them were a pollinator's buzz. Spectrum does not name the species: it sorts every buzz by wingbeat frequency, lower for large insects such as bumblebees, higher for small ones.

What the data looks like once it is in XNatura
Every reading lands in the site's digital twin, next to the satellite layers and the surveys, and reads as a chart, not as a file.

FAQ
Frequently asked questions
How does pollinator detection work?
Spectrum uses a high-sensitivity MEMS microphone to capture the sound frequencies produced by the wingbeat of insects within a 3-meter radius. Machine learning algorithms then classify the insects into 19 distinct clusters.
How long does the sensor's battery last?
Thanks to the integrated solar panel, Spectrum has virtually unlimited autonomy under normal irradiance conditions. In case of total absence of sunlight, the internal battery guarantees 3 months of operation.
What are the 19 clusters?
The clusters are groupings of pollinators based on the acoustic characteristics of their wingbeat frequencies. We do not identify individual species, but classify insects into 19 distinct categories representing different types of pollinators.
Why is the range only 3 meters?
The 3-meter range is optimized to ensure maximum accuracy in detecting wingbeat frequencies. This allows high-quality data capture without environmental interference, ensuring accurate classifications.
