The air quality problematics and use of the indoor air quality sensors for monitoring indoor air quality and for efficient ventilation control and energy saving.
With the increasing pressure of energy saving for heating, ventilation and air conditioning and with the increasing pressure to reduction of the carbon dioxide emissions the buildings are built more and more tight and with better thermal insulation. These steps are technologically correct and now on reasonable maximum, this time is not economically beneficial to improve thermal insulation and tightness of buildings. This trend causes the need to handle an indoor air quality to have comfortable and healthy indoor environment. According to the most recent surveys we spend on average 80 to 90 % closed indoor.
So it is really necessary to ensure supply of an appropriate amount of fresh air into the indoor spaces in the way to reach the comfort environment and at the same time to save energy necessary for heating, ventilation and air conditioning of buildings.
The best approach is to use appropriate ventilation units controlled by internal air quality sensors. The goal of using air quality sensors is to increase indoor comfort and at the same time to spare energy for heating, conditioning and ventilation of buildings. Using the sensors the units ventilate only at the time when it is really needed.
In some cases it is sufficient to monitor CO2 concentration, in another cases is better to monitor volatile organic compounds – so called VOC. The rules always sticks to choose appropriate type of sensor according to prevailing source of air pollution in the particular case because of giving a most relevant information to the ventilation system about the indoor air quality.
Dust sensor with IQRF module
We introduce new type of sensor with integrated IQRF module, it is so called PM sensor. The PM means Particulate Matters sensor, the common definition of PM includes dust particles that are smaller then 100 micrometers and no smaller than 100 nanometers in size.
Basically the smaller the particles are, the deeper they can penetrate through our respiratory system and into our bloodstream, posing a higher hazard to our health. The World Health Organization (WHO) reports airborne particulate matter as a Group 1 carcinogen and as the biggest environmental risk to health.
