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.
