Hawa Dawa launches area-wide immission register on nitrogen dioxide immissions in Germany

How high are nitrogen dioxide immissions in Germany? Are we making progress with the much-invoked transport, energy, and heat turnaround, the urgent reduction of fossil combustion processes and the elimination of climate-damaging emissions? And – if so – which kind of relief for people, nature and the environment will be the result and at what pace, in which regions? These questions are increasingly occupying politicians, administrators, researchers and citizens. Now Hawa Dawa presents a new approach that leverages multiple advantages of new technologies to enable a higher spatial and temporal resolution of air pollution data. The immission register thus has the potential to form the business intelligence basis for a data-based transport turnaround and climate policy. Read more

Measuring air quality with IoT sensors: compliance with mandatory quality standards (Directive 2008/50/EC)

“State environmental agency finds serious quality deficiencies at measuring station” – so read at the end of last year (rbb24). What at first reads like a damning verdict for technologically new measuring methods raises various questions when considered more comprehensively: What is the standard for the quality of an air measuring device? What quality standards must be maintained if public money is spent on them?

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 ).

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.

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.

Frische Luft durch neue Technologien: wohin die Reise gehen kann

Dicke Luft, gesundheitliche Risiken, Fahrverbote: Die Luftverschmutzung in den großen Städten wird zu einem der dringendsten Umweltprobleme unserer Zeit. Immer häufiger überschreiten die Grenzwerte für Schadstoffe – etwa Feinstaub  oder Stickstoffdioxid – die gesetzlichen Limits. Die Städte erteilen dann Fahrverbote auf wichtigen Strecken, doch der Ärger der Pendler bleibt groß, die Schadstoffbelastung ändert sich kaum und die Gefahr von Atemkrankheiten steigt weiter. Die Luftverschmutzung plagt fast alle Länder dieser Welt – und dennoch ist das Bild, das wir von der Luftqualität haben, sehr unscharf und widersprüchlich. Der Grund hierfür ist, dass nur an vereinzelten Orten gemessen wird. Die Messstationen mit der Größe einer Garage sind zudem sehr teuer und daher leisten sich die verantwortlichen Umweltbehörden nur wenige Messstationen. Das Wissen über die tatsächliche Luftqualität ist damit erschreckend lückenhaft. Read more
