The reference in high-precision outdoor monitoring
The WT1 Lite is the perfect all-in-one system designed for in-depth understanding and effective control of your outdoor environment. It offers simplified configurations compared to the WT1 Pro and is especially suited for smart cities and industrial environments requiring advanced monitoring of emissions at the fencelines or periphery of sites. With its customizable features, the WT1 Lite enables precise quantification and identification of emissions, while capturing real-time physical, chemical, and perceptual data (gases, odors, particles, etc.).
The WT1 Lite allows for continuous and simultaneous monitoring of a wide range of sensory parameters, adjustable to meet your specific needs. Whether you are involved in waste management, smart cities, or other industrial sectors, the WT1 Lite stands out for its exceptional adaptability to accurately meet your monitoring requirements.
When integrated with the EllonaSoft platform, the WT1 Lite provides real-time alert systems for proactive emission management. It also allows, via the API, the triggering of remediation actions. This enables decision-makers not only to receive immediate alerts but also to initiate appropriate corrective actions to optimize environmental management.

Cutting-edge features
Analyze in real time
By transforming raw data into actionable insights, Ellona’s environmental intelligence platform provides enriched data, facilitating effective and impactful actions for businesses and communities.
Identification
Les algorithmes IA et les bases de données développés par Ellona permettent non seulement de quantifier des odeurs ou des particules mais aussi de les identifier.
Emission model
Ellona offers a dispersion software that integrates weather data and models the impact of a site’s emissions on its surroundings.
Alerts & notifications
The Ellona platform enables the configuration of various real-time alerts and the automation of smart report generation, thereby facilitating decision-making and the initiation of remediation actions.
Triggering of remediation systems
This feature, integrated with the WT1 Lite, allows for the automation of triggering third-party systems (such as misting, ventilation, etc.) through precise control via the API. This automation ensures a swift and appropriate response in the event of a detected incident.
Feedback on human perception
Ellona’s solutions include a feature that allows individuals to provide real-time feedback on their environmental perceptions, enabling the adjustment of analysis algorithms.
