Market overview

The pandemic of Covid-19 has clearly shown that air-borne diseases spread at a tremendous speed – this is especially true in our current model of urban society, where density of people per square meter is high.

Daily commuting to job, enterprises sites concentrating their workers in offices, students in packed rooms from kindergarten to schools to universities are all situations where a lot of people occupy a quite limited space. But not only work- or study-related activities show such high density: also, in our free time we tend to gather and go to cinemas, theatres or museums, busy gyms, crowded sports halls, or restaurants.

Covid-19 and other similar diseases travel often as aerosols when we breathe. When a person talks, shouts, sneezes of coughs aerosols are created. In enclosed spaces, these particles can remain suspended in the air for hours. To reduce the spread of viruses, it is necessary to renovate the air in those spaces, and remove the “used”, CO2-loaded air we produce.

As most usually this ventilation is obtained by keeping windows open continuously, the energy consumption skyrockets trying to keep the target temperature that was set in the heating and air conditioning systems. This extra usage of energy brings additionally a negative effect on the environment.

Ventilation must be done at the precise moments when the CO2 levels indicate it. To monitor the efficiency of indoor ventilation, avoid contagions and reduce energy waste, CO2 meters need be installed, as the information obtained of their measurements, combined with specific room data, provides indication to ventilate the room.

What are the important points related to air quality monitoring?

Advanced air quality monitoring systems provide the best features for a range of use cases, based on several key aspects.

  • Accuracy

    Higher accuracy directly translates into allowing the best decision possible – with bigger savings in energy efficiency.
  • Sensor technology

    State-of-the-art sensors measure not only CO2 but also other data such as humidity and temperature.
  • Data presentation and notifications

    Intuitive, actionable data presentation and smart notifications allow for clear indications regarding ventilation needs.
  • Easy installation

    Plug & play installation facilitates deployment and minimizes staff training needs

IoT-based solution for air quality monitoring

Be.Air is designed with the principles of easy deployment and high quality in mind, all within one compact solution.

State-of-the-art technology based on the principle of photoacoustic detection allows be.Air sensors with an ultra-small size and high performance, while advanced signal processing ensures high precision and low noise.

The sensor is located inside the IoT gateway thanks to its small size. In addition, each sensor has an action range of up to 250 m3.

The solution’s brain is a robust, compact, “Made in Germany” automated IoT gateway, which sends the data captured by the sensor to the cloud, where the be.Air platform resides, through 4G/LTE connectivity thanks to the eSIM in the IoT gateway.

As the IoT gateway can be wall-mounted easily, installation is both fast, discrete, and very efficient.

The cloud-based platform provides then reports and intuitive data via app; customization of user profiles and air quality parameters thresholds are possible, offering a situation-specific solution for each use case.


As a result, an optimized maintenance of air quality helps fight Covid-19 spread, while adding peace of mind to end customers; from a business perspective, cost savings in energy consumption are achieved:

  • 24x7 active air quality monitoring

    based on several key parameters provides real-time, accurate data – with precise insights and recommendation to trigger on or off ventilation
  • End-users’ peace of mind

    helps keep consumers and a stable, predictable flow of users: added value to the business owner
  • Cost savings

    thanks the reduction to the true minimum the loss of energy due to ventilation of the building or room: exactly when it is truly most efficient
  • Business regulations compliance

    due to ventilation effectiveness check in accordance with occupational safety regulations (current or soon applicable, per country).
