TÜV Süd confirms Hawa Dawa the accuracy of the “indicative measurement”

IoT measurement method meets legal requirements to prove compliance with air pollutant limits.

Hawa Dawa has been the first provider in Europe to be certified by an independent state-approved body for the legally prescribed measurement accuracy of its IoT sensor measuring networks. TÜV Süd certifies:  Hawa Dawa achieves the quality objectives of the 39. BlmSchV  (the national implementation of the EU directive 2008/50/EG ).
In the evaluation, TÜV Süd used measurement data of a period of 12 months. For this purpose, the NO2 (nitrogen dioxide) values measured by Hawa Dawa were compared with the values of an official measuring station.

Winter in Germany

The winterly weather conditions made the difference in handling and convenience particularly obvious. While tube collectors require a lot of manual handling – including collecting them one-by-one – the Hawa Dawa solution delivers the air quality information conveniently to your desk.
This is only one of the benefits. Additionally, traditional tube collectors deliver one average value of NO2 concentration per month, whereas Hawa Dawa includes PM2.5, PM10 and O3 real-time values at any time.
And the cost? The total cost of ownership for the Hawa Dawa solution is about 50% of the tube collector’s cost.

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.
