Analyse in real time

By bridging the gap between raw data and actionable information, Ellona’s environmental intelligence platform provides you with augmented data for meaningful and impactful actions for businesses and communities.



The AI algorithms and databases developed by Ellona allow not only to quantify odors or particles but also to identify them.


Quality Index

The Ellona solution allows to combine the measurements of different parameters and proposes decision support indices: containment index, viral index, etc.


Alerts & notifications

The Ellona platform allows to set different types of alerts in real time and to automate the generation of intelligent reports.


Automatic triggering of remediation

Thanks to the API integrated into the platform, Ellona’s solution can automatically trigger various third-party systems such as: ventilation, heating, window opening, etc.


Feedback on human perception

Ellona’s solutions integrate a function allowing individuals to report in real time their perceptions of the environment to adjust the analysis algorithms.
