Indoor air quality

Closed rooms, stale air, and no possibility of ventilation – lack of air quality has not only been a major issue since the Covid pandemic. In this blog, we show you how clever sensor technology and cloud technology contribute to the transparency of air quality.

 

Work efficiency and satisfaction of employees, the utilization of office and conference rooms and energy costs, all this is influenced by the quality of indoor air. Even more important: clean air. Because wherever people meet in closed rooms, be it in schools , universities or in the office, the quality of the air is a sensitive issue. The technology for indoor air measurement is now easy to install and operate. The sensors, which are simply affixed into the rooms by plug-and-play, are connected to their own cloud by a network independent of normal Wi-Fi (LORA-WAN) and a gateway. There, the values are processed and can be read at any time by an online dashboard.

We show you some positive effects of this technology:

  • Well-being and performance increase: The quality of the ambient air has a measurable influence on our work performance during concentrated learning and working. Tiredness, lack of concentration or even headaches are the consequences of poor air quality. The sensors can detect the decisive parameters responsible for the poor air quality. In this way, carbon dioxide (CO2), temperature, humidity and volatile organic compounds (VOC) can be recorded, and conclusions can be drawn about the humidity, and even about the germ and aerosol content of the room air. If required, other parameters can also be recorded by the technology, such as particulate matter, radon, or carbon monoxide.
  • Measuring room layout: Exceedances of limit values are reliably recorded by this technology and can be displayed transparently in real time. This makes it possible to determine the number of people in a room anonymously and without the use of cameras. This can be used, for example, to determine a current overcrowding or a chronic over- or under-utilization of capacity limits. All of this can be done without collecting any personal data.
  • Take action measures: By providing the values directly, action instructions can be derived, which are made visible in the affected rooms with the help of light pulses, like a kind of traffic light. The measured values are also fed into the cloud via device management over a separate network. There, the data is processed, analyzed, compared, and made available via an online dashboard. This not only gives those directly affected an insight into the values, but also other authorized persons, such as managers or air conditioning technicians.

Measuring and controlling indoor air quality makes sense in many ways. With the currently available technologies, the systems can be installed quickly and cost-effectively. We’d be happy to support you.
