Hawa Dawa establishes a local network for measuring air quality in the city of Seelze

Hawa Dawa has been commissioned by the city of Seelze to establish a local network of IoT (Internet of Things) measuring instruments. A total of three Hawa Dawa Sentience air measurement devices will provide hourly values for nitrogen dioxide (NO2), ozone (O3), and particulate matter (PM2.5 and PM10) in places identified by the city of Seelze as useful.

 In the city of Seelze live 36,000 inhabitants on an area of 54 square kilometres. Seelze neighbours directly to the west on the state capital of Lower Saxony, Hanover. There are no permanently installed public measuring stations in the city of Seelze. Temporary measurements did not show that the official threshold value for NO2 of 40.0 micrograms per m3 was exceeded. Nevertheless, the city of Seelze is aware of the health risks posed by polluted air even below the legal limit and has decided to actively address this problem. The first step is to obtain clarity on the current air quality.

The Hawa Dawa solution for Seelze presents the measured values close to real-time in digital form on an interactive dashboard. Monthly reports provide in-depth insights into patterns and timing, taking into account temperature and wind data. By using Hawa Dawa IoT air measurement devices, Seelze can determine the locations where the measurements will be made, taking into account local requirements. The Hawa Dawa PRO Dashboard used by Seelze enables additional insights on air quality in Seelze to be gained through a heatmap display – after all, information about the places where people are actually staying are crucial.

Karim Tarraf, CEO of Hawa Dawa, explains: “Many smaller to medium-sized cities are in the situation of Seelze, that there are no public measuring stations. The decision-makers do not have up-to-date information on the impact on air quality caused by traffic and other issuers. We believe that local air quality facts are a prerequisite for taking effective action against air pollution and protecting the population. Here, mere measurements are not sufficient, but it is imperative to analyse the data in context. We are pleased to support the city of Seelze in this project.”

Better urban air quality does not need drastic measures – but a meaningful database for decisions

Hawa Dawa has been commissioned by Stadtwerke Mainz with an innovative and result-driven project: creating a sustainable data-based decision-making basis. Hawa Dawa will propose stepped measures to improve urban air quality based on their projected impact on air quality, applying data-based analyses, and forecasts. For this purpose, an intelligent infrastructure for collecting environmental and traffic data as well as a data platform for evaluation is established. Read more

Cities at the Forefront of Air Quality: Interview with Karim Tarraf, CEO of Hawa Dawa

In the days of Covid-19, “air quality” is a topic in the media, too. Cities are often pioneers in pushing for improvements.

Here’s an interview with Karim Tarraf, CEO of Hawa Dawa, in which he comments on the following topics:
  • How can the increasing importance of air quality data be explained?
  • Why are the available measurements and data usually insufficient?

Cities are the future of humanity. More than half of the world’s people already live in cities; in Germany, it is as much as 70 percent. They are all looking for security and prosperity, education and networking and the urban lifestyle, in short: quality of life. In a limited space, more and more people want to take advantage of the chances of a good life. Social division must be avoided and a sustainable use of natural resources must be achieved. Thus, all areas from waste to energy, governance, mobility and water supply are relevant in the process of sustainable urban development towards a smart city of the future.
