Analyze 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.


Dispersion Model

Ellona proposes a dispersion software allowing to integrate weather data and to model the impact of the emissions of a site on its neighborhood.


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 integration of ON/OFF and 4-20 mA switches in the WT1, the Ellona solution allows to automatically trigger different third party systems such as: sampling, misting or ventilation ramp, 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.
