A one-of-a-kind approach for your operations

Real-time multi-variate analysis.

With our environmental intelligence platform, Ellona transforms raw data into actionable insights with unparalleled precision. By processing data updates every 10 seconds, we continuously analyze a wide range of variables. Our unique strength lies in multi-variate analysis, which provides a comprehensive and deep understanding of the phenomena at hand, leading to more effective and impactful actions for businesses and communities.

Identification and triangulation of footprints and sources.

The artificial intelligence algorithms and databases developed by Ellona go far beyond simple quantification. We excel in the precise identification of odor, gas, and particulate sources, whether they are dispersed in the air or concentrated in specific locations. Data triangulation is at the core of our approach, allowing us to cross-reference information and pinpoint these sources with high accuracy in indoor environments.

Indoor air quality indices.

The Ellona solution integrates precise measurements of multiple parameters, such as odor levels, gases, fine particles, temperature, and humidity. These data are then analyzed to generate decision-support indices, such as the confinement index, which assesses ventilation and pollutant accumulation, and the viral index, which estimates the risk of pathogen spread in indoor air. With these indices, managers can take proactive measures to ensure a healthy and safe indoor environment.

Smart alerts and customized notifications.

Our platform allows for real-time configuration of various types of alerts tailored to each user’s specific needs. Additionally, the automatic generation of smart reports ensures optimal responsiveness to any critical situation.

Automation of remediation systems.

Thanks to the integrated API, the Ellona solution provides proactive management of indoor air quality by automating the activation of third-party systems. Whether it’s for ventilation, heating, window opening, or adjusting air purification systems, our solution ensures a rapid and effective response based on detected variations in the indoor environment. This helps maintain optimal conditions in real-time, reducing indoor pollution risks and ensuring increased comfort and safety for occupants.

Integration of human perceptions via QR codes.

Ellona enhances its analyses by integrating human perceptions collected via QR codes. These subjective data are then correlated in real-time with the technical data collected by our systems, providing a comprehensive and nuanced view of the situations for even more precise interventions.

Your questions, our solutions

How to accurately measure, identify, and locate noise indoors?

Indoor noise management is essential for safety and comfort. It’s not just about measuring sound levels but also accurately identifying the sources and nature of the noise to tailor remediation strategies.

Ellona’s POD2 devices play a key role in acoustic monitoring and indoor safety, whether in offices, hospitals, factories, schools, or commercial spaces.

Continuous measurement of sound levels to ensure a compliant environment
Identification of noise sources (machines, voices, barking, alarms, ventilation…)
Detailed analysis of the nature of the noises (impulsive, resonant, mechanical…)
Detection of critical noises (gunfire, security alarms, glass breakage, technical incidents…)
Targeted remediation to secure infrastructure and protect people

With EllonaSoft, data is centralized, analyzed, and utilized in real-time, enabling fast and efficient decision-making in the event of an incident.

How to accurately measure, identify, and locate odors (odours) indoors?

The management of indoor odor (odour) nuisances is based on three essential aspects:

Real-time odor (odour) detection to identify any anomalies
Measurement of odor (odour) intensity to track their evolution and impact
Accurate identification of the nature of odors (odours) and their sources for quick and targeted remediation

Ellona’s POD2 is an advanced solution that continuously analyzes indoor air through a combination of MOS sensors and smart algorithms. This enables the anticipation and effective management of odor (odour) nuisances in sensitive environments such as offices, hospitals, laboratories, industrial kitchens, or commercial spaces.

All collected data is centralized, analyzed, and utilized through the EllonaSoft platform. This powerful tool enables real-time monitoring, rapid identification of odor (odour) nature and sources, and optimization of remediation strategies, ensuring better control of odor (odour) nuisances and healthier indoor air.

How to measure, identify, and locate fine particles, including PM1, PM2.5, and PM10, indoors?

Ellona’s POD2 enables real-time indoor measurement of fine particles (PM1, PM2.5, PM10, and down to PM0.3) using optical sensors. These sensors detect and count particles by measuring light scattering, providing precise air quality monitoring. In addition to measuring particle concentration, the POD2 leverages artificial intelligence algorithms to identify their nature and source, helping to better understand pollution origins and optimize remediation actions. Data is centralized and analyzed via EllonaSoft, ensuring optimized health risk management and real-time monitoring to protect occupants’ safety.

The POD2 specifically monitors fine particle levels in line with WHO recommendations:

PM2.5: ≤ 5 µg/m³ (annual average exposure)
PM10: ≤ 15 µg/m³ (annual average exposure)
PM1: Few official guidelines, but high concentrations can be concerning.

This capability of measurement, analysis, and identification enhances the understanding of indoor pollution challenges and enables the effective adaptation of air quality improvement strategies.

How to measure, identify, and precisely locate gas emissions indoors?

Ellona’s POD2 ensures the safety of people and infrastructure by monitoring indoor air quality through real-time multivariate analysis. It measures up to 5 gases simultaneously (4 electrochemical sensors + 1 optical sensor) from a list of 21 possible gases (NO₂, SO₂, CO, O₃, NH₃, etc.). Its artificial intelligence algorithms accurately identify gas types, detect their interactions, and locate their sources. Through the EllonaSoft platform, smart alerts and automated corrective actions (ventilation, air purification) are implemented, ensuring a healthier environment, optimal occupant protection, and infrastructure preservation.

Is the analysis of NH3 and H2S molecules enough to qualify and quantify odors (odours)?

No, the analysis of H₂S (hydrogen sulfide) and NH₃ (ammonia) molecules is not sufficient to assess all odors (odours) present in an environment. Although these molecules are commonly analyzed using electrochemical sensors, they only represent a fraction of the odor (odour) compounds. Hydrogen sulfide and ammonia are indeed important components of certain odor (odour) nuisances, but many other chemical compounds are responsible for varied and complex odors, such as aldehydes, volatile fatty acids, and mercaptans, which are not detected by these traditional technologies. This is precisely what the MOX (Metal Oxide Semiconductor) sensors used in Ellona devices, such as the WT1 Lite, the WT1 Pro (specifically designed for outdoor use), and the POD2 (adapted for indoor environments), are capable of detecting.
