The citizen information of Hawa Dawa enable municipalities to digitally provide information on air quality to citizens in a moderated way. Citizen information is becoming increasingly important: on the one hand, because today’s information media have created a new standard, which is expected as the usually available information, and on the other hand, because those affected would like to form their own opinion on pressing, important issues, which is based on up-to-date data.

Hawa Dawa is working with Westenergie AG’s Smart Pole Factory. In a project of the company in Essen, Hawa Dawa Sentience air measuring devices are installed in smart pole lights.
Hawa Dawa becomes part of the project zukunftskommune@bw in the city of Ulm
Hawa Dawa was awarded the contract within the public tender for the procurement of LoRaWan-capable air/climate sensors in the Eselsberg project area in the city of Ulm. Hawa Dawa will install a network of several Sentience air quality measurement devices, develop a comprehensive display from the measured values and feed the data via API into the Ulm data platform, which is currently under construction. The data will be made available as open IoT data. Read more
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
Hawa Dawa has completed a study on the impact of traffic on air quality in a town in southern Germany.
Hawa Dawa, in collaboration with Siemens Mobility and ryd, have demonstrated the effectiveness of an eco-routing pilot launched at the end of 2018.
Hawa Dawa, in collaboration with Siemens Mobility and ryd, have demonstrated the effectiveness of an eco-routing pilot launched at the end of 2018. The four-week pilot project “Clean Air in Munich” (SLIM) tested whether data-based route recommendations based on predicted pollution levels have an influence on the route choice of Munich drivers.
