Challenge / Goal
In the urban area of Seelze, there are no permanent installed public measuring stations. Temporary measurements did not show that the official threshold value for NO2 of 40.0 micrograms per m3 was exceeded.
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 the issue by implementing new measures. Therefore better data accessibility and display were needed.
Solution
Hawa Dawa established a local network of IoT (Internet of Things) measurement devices in Seelze. A total of three Hawa Dawa Sentience air measurement devices 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. 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 measured values are presented close to real-time in digital form on an interactive dashboard. In addition, monthly reports provide in-depth insights into patterns and timing, taking temperature and wind data into account. 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.
