German’s Seelze establishes IoT network to measure city air quality


The German city of Seelze has selected Hawa Dawa to deploy a smart city initiative designed to protect citizens’ health from negative environmental influences. Hawa Dawa will establish a local network of Internet of Things air quality measuring instruments.

Three sentience air quality 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.

Previously there were no permanently installed public air quality 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 smart city project will enable the city of Seelze to access measured values close to real-time in digital form on an interactive dashboard. Monthly reports will provide in-depth insights into patterns and timing, taking into account temperature and wind data.

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.”
