Combined sensors are designed for measuring indoor air quality, where they allow the measurement of several physical variables simultaneously. According to the measured values of the monitored variables it is then possible to control ventilation units. The advantage of combined air quality sensors is very simple and economically inexpensive installation in air distribution systems.
Humidity is a meteorological element that describes the amount of water vapour in the air, which is mainly contained in the lower atmosphere and is produced by evaporation from large bodies of water, soil, plants, animals, etc.
The company took air quality measurements in a bedroom where several people were sleeping. The measurements were taken at different ventilation levels. However, in neither case were the results satisfactory. Read the full article to find out why you can't get to sleep during the night and wake up tired in the morning.
Low-energy houses have been the focus of attention for many years. Their development is of course linked to the increase in energy prices that can be observed in recent years. It is generally stated that the savings in heating costs are approximately half in a low-energy house compared to a conventional building.
Indoor air quality is nowadays assessed, if at all, by temperature, humidity and carbon dioxide (CO2) concentration. However, people often complain about air quality even though all these indicators are at optimum levels. So what substances further degrade air quality?
Getting lost in technical terms related to measuring the concentration of various substances in the air? Sensors for measuring CO2, CO, VOCs etc. work on three basic principles, the most commonly used of which is the NDIR principle. What does NDIR mean and how do sensors work on this and other principles?
