To sustainably improve citizens’ quality of life while strengthening community resilience.

Monitor, understand and optimize urban environments in real time.

Smart cities are now facing major environmental, public health, and security challenges. Air pollution, noise pollution, odour emissions, urban heat islands, road traffic, indoor air quality in public buildings, environmental incident management, and the protection of critical infrastructure are all complex issues that require continuous, intelligent monitoring.

In this context, access to reliable, real-time, and actionable environmental data has become essential, enabling local authorities, metropolitan areas, and urban operators to make fast, informed, and measurable decisions.

Smart Cities must also address growing challenges related to territorial security and urban resi

lience.

Environmental incident detection, critical infrastructure monitoring, technological risk management, public space security, anticipation of critical situations, and the protection of citizens all require tools capable of delivering a comprehensive, reliable, and real-time environmental picture of the territory.

At Ellona, we support Smart Cities in their environmental transition through advanced real-time monitoring solutions for gases, odours, particulate matter, noise, and environmental parameters. Our technologies go beyond measurement: they enable users to identify, locate, understand, and anticipate environmental phenomena and their evolution.

Through its advanced monitoring technologies and intelligent analytics capabilities, Ellona helps strengthen territorial situational awareness and improve the responsiveness of public authorities to environmental events and risk situations.

Our monitoring devices, combined with the EllonaSoft platform, provide a comprehensive and dynamic view of urban environments, helping improve citizens’ quality of life, enhance the security of critical infrastructure, and optimize urban and territorial management.

Real-time multivariate analysis

Thanks to our Environmental Intelligence platform, Ellona transforms raw environmental data into actionable insights with unmatched precision. Powered by data collected every 10 seconds, our platform continuously analyses a wide range of environmental parameters in real time.

Our unique expertise lies in multivariate analysis, enabling a comprehensive understanding of complex urban phenomena, including air pollution, odour nuisances, noise, isolated environmental events, traffic peaks, and environmental incidents.

Identification and triangulation of fingerprints and emission sources

Ellona’s artificial intelligence algorithms go far beyond simply quantifying pollutants.

Our technology accurately identifies environmental fingerprints and emission sources, including road traffic, industrial facilities, construction sites, transport networks, commercial activities, and isolated environmental events.

By combining advanced analytics with data triangulation, Ellona precisely locates environmental phenomena, enabling local authorities to respond faster and make more effective, data-driven decisions.

Dynamic emission modelling

Ellona provides advanced dynamic modelling tools that integrate real-time meteorological data.

This approach enables the simulation and visualization of the dispersion of pollutants, odours, and particulate matter across urban environments, helping anticipate their impact on populations, critical infrastructure, and the surrounding environment.

Smart alerts and customized notifications

Our platform enables the configuration of real-time alerts tailored to the needs of local authorities, urban operators, and technical teams.

Alerts can be configured based on:

Regulatory thresholds
Specific environmental events
Identified environmental fingerprints
Critical or unusual situations

Automated intelligent reporting ensures rapid response, improved incident management, and more informed decision-making.

Automatic triggering of remediation systems

Ellona enables the automation of corrective and preventive actions by automatically triggering third-party systems, including:

Ventilation systems
Air purification systems
Dust suppression systems
Misting systems
Area access control and closures
Dynamic traffic management
Intelligent signage

This level of automation can be achieved through APIs, digital ON/OFF outputs, or 4–20 mA interfaces, ensuring seamless integration with existing infrastructure.

Citizen feedback integration through QR codes

Ellona enhances its environmental intelligence by integrating human observations collected directly from citizens.

Through QR codes or dedicated reporting interfaces, residents can report:

Odour nuisances
Environmental nuisances
Noise disturbances
Unusual environmental events

These observations are automatically correlated in real time with the technical data collected by our monitoring devices, providing a more comprehensive, contextualized, and actionable understanding of environmental conditions.
