First Hawa Dawa measurement device deployed in the USA: plug-and-play

/in /by

We are proud to have our first Sentience Measurement Device installed in the USA (Sacramento). It is a significant step to enter business in a country on another continent.

Additionally, the installation and deployment of the device provided evidence that our processes and technology are professionally defined and elaborated. So, in California, it was a true plug-and-play installation: The customer followed the steps in our installation manual, and the Sentience device just started working and provided data.

The Sentence device was installed and deployed thousands of miles from our home base with zero issues. This demonstrates that our hardware, connectivity options, and processes are robust and 100% ready for standard field roll-out:

  1. A detailed installation handbook supports our customers for a smooth self-setup
  2. Our remote performance monitoring works beyond borders and would detect issues immediately
  3. Our connectivity options (LoRaWAN, GSM/EDGE, and LTE-M) are ready for global use.

Saving energy while protecting the climate?

/in /by

The times when climate and environmental protection were always clearly on the “good” side are over. In the real-life implementation, alternative energies collide with nature conservation and species protection, as, e.g. in the case of off-shore wind farms. The discussion about “clean” nuclear energy is also difficult. In general, this means that one must take a closer look, weigh up the (long-term) impacts and evaluate the planned measures accordingly in a comprehensive manner. 

There are also side aspects to consider regarding air quality measurement. It is almost a paradox when air quality is measured by driving vehicles through the city. If the car has an electric drive, this has, at best, a NO2-reducing effect. The fine dust pollution from brake and tyre abrasion remains. And the environmental problems associated with the production of the necessary car batteries are widely known. 

A very topical issue at the moment is energy supply and energy consumption. There are also substantial differences in energy consumption of air quality measurements. The containers that operate the public measurements have an annual energy demand of 3,500 kWh to more than 11,000 kWh, depending on the equipment. This means that even the more economical measuring stations consume more than a typical 2-person household.  

With the Hawa Dawa measuring devices, the energy-consuming conditioning of the air before measuring is taken over by a calibration algorithm through the innovative use of artificial intelligence. This means that the annual energy consumption of our measuring devices is at the level of a standard household freezer – i.e. a fraction of the energy that has to be provided for a measuring station. 

The air measurement network in Mainz continues to operate

A comprehensive base of environmental data as a basis for eco-sensitive measures

Hawa Dawa is entering the third year of Mainz’s sensor-based air measurement network with Mainzer Netze GmbH. The monitoring network in Mainz will create one of the most comprehensive urban collections of environmental information.

By continuing to operate the measurement network and making the data available via open standards, infrastructure is being established in Mainz on which future measures – for example, environmentally sensitive traffic management – can easily be based at any time. In addition, new approaches can be developed based on this extensive data collection, which, for example, take a cross-sectoral look at the cause and effect fields of environment, weather, traffic and health. Last but not least, the digitally available data is an efficient basis for the creation and updating of clean air plans. Analyses can be drawn from the information quickly and narrowed down to any period or geographical area.

All environmentally relevant measures will benefit from the depth of the data and its quality: Hawa Dawa measurement networks provide an advanced tool to capture air quality digitally, spatially and temporally with high resolution. The present test report from TÜV Süd, which also includes a Mainz comparison station with the measuring station of the Rhineland-Palatinate State Office for the Environment on Parcusstrasse, proves the quality of the measuring method.

Martin Montag, Head of Sales Public Sector at Hawa Dawa, explains: “We congratulate Mainz on what is probably the best data basis in a national comparison. Better information is the basis for better decisions. Short-term measurements are only of limited use to justify sustainable measures because seasonal influences or special influences in one year can hardly be considered properly. In Mainz, we are taking on the role of a pioneer who has recognized this.”

 

When regulations become real citizen benefits

Proven regulatory-grade accuracy of the digital method of measuring air quality opens up new opportunities for public services

Hawa Dawa has been confirmed by TÜV Süd to apply a digital measurement method, which is suitable for carrying out measurements according to the German Federal Immission Control Act (39th BImSchV – the German national legislation enforcing EU Directive 2008/50/EC). TÜV Süd evaluated the Hawa Dawa method based on a comparison with suitability-tested measuring equipment.

Hawa Dawa is the first provider of so-called low-cost measurement methods confirmed to carry out measurements according to regulatory standards. This is particularly important because the application of low-cost sensors for measuring air pollution is new. There are still no guidelines for quality requirements, quality assurance and application. The scope of testing for the qualification of air quality measuring instruments based on electrochemical sensors is currently still being discussed and coordinated in VDI committees. Here, too, Hawa Dawa is involved. Read more

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

/in /by

“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?
