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.”

Hawa Dawa provides data-based decision-making platform to reduce urban traffic-induced emissions in Mainz

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

Hawa Dawa successfully hosted the “Smart City Meetup” in Munich

Hawa Dawa hosted their first “Smart City Meetup” on January 29. With exciting presentations and a high-level keynote from Fraunhofer Morgenstadt Initiative, Hawa Dawa was able to attract a wide audience – reaching from Smart City solutions providers, representatives from cities to interested citizens.

The objective of this event was on putting spotlights on the various aspects of the topic  “Smart City” and to provide a space for networking and exchange of ideas. The event focussed on the areas of “Smart City and air quality – the framework, impact and trends” and “Artificial intelligence and machine learning – working principles, applications and chances”. In his keynote speech on “Smart City – between technical capability and public needs” Dr Alanus von Radecki of the Fraunhofer Morgenstadt Initiative showed fascinating examples and provided exciting food for thought. After the presentations, the audience got engaged in lively and committed discussions with the Hawa Dawa experts and the invited speaker.

Karim Tarraf, CEO and co-founder of Hawa Dawa, says: “We are very pleased with this great audience and we feel strongly encouraged by the high interest in the topic ‘smart city’ and its contribution to sustainability and healthier environment.”

About Fraunhofer Morgenstadt:

In the “Morning City Initiative”, the Fraunhofer Society develops the solutions for the city of the future together with partners from industry and municipalities.

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.

High levels of significance found in the correlation of air quality data with traffic and weather data: Hawa Dawa concludes an extensive on-site data study


Hawa Dawa has completed a study on the impact of traffic on air quality in a town in southern Germany. The team collected data on air quality and traffic volume in the field and then correlated these values in-house. The aim of the study was to investigate the diverse effects of traffic and weather on air quality levels and pollution behaviour. A further hypothesis tested as part of the study was the extent to which speed limits or speed recommendations have an positive influence on air quality. Read more
