Technical Background for Air Quality Sensors

Since the emissions scandal involving diesel cars from various manufacturers, urban air quality has come to the attention of many and air pollution is also being discussed in new aspects in connection with the Covid-19 pandemic. At the same time, the range of equipment for measuring various air pollutants is very large and also confusing, especially in the area of inexpensive solutions. It is not easy to keep track and see if it is a product that can fulfil the intended purpose.

At Hawa Dawa, we have been producing a measuring instrument and system for comprehensive air quality measurement for several years. The development of our «Sentience» measuring instrument was driven by the claim to provide a reliable device at a price through the use of new technologies, which also makes wide and tight-meshed coverage possible.

In the following, we would like to try to present the technical complexity of air-pollutant measurement in a simple way and to give indications on this basis, which limits the individual devices and methods have. If you can’t stand it, you will find a link to download a short checklist at the end of the article.
