Test Measurements of AQE Alpha version device
In the framework of second Urban Hackathon (UH-2) and as a part of Environmental activities co-financed by the municipality a pilot project was executed under the moniker of Air Pollution Egg (APE) by the Maribor Cycling Network and the Citilab Institute. By using modular component sensors (Arduino AQE sensor shield) and special optical dust sensor a device was conceived with the ability to measure environmental parameters inside the <15% variation when tested next to the official dislocated measuring station (Titova cesta, Maribor).
Next graphs show typical measurements that were taken on Koroška Street on working day of the last week (19. – 23. 10.) of the ETM on the following location.
Test NO2 measurements inside the 12h period (8AM-8PM), data in PPM:
Test CO measurements inside the 12h period (8AM-8PM), data in PPM:
Dust particle measurements (cumulative >PM2.5) inside the 12h period (8AM-8PM), data in mg/m3:
The measurements show small deviation from typical street measurement. No excess pollution was measured in traffic peak times around 8AM and 5PM (i.e. dust and NO2). At the time of the ETM two building sites were active on the Koroška Street, that had a negative impact on the dust pollution measurements. At the time of the measurements no excess pollution was detected. Subsequent measurements, that are taking place now, show breaches of allowed levels in NO2 and dust pollution.
In the framework of APE project measurements on the Koroška Street will continue. All the data will be published on the web (koroskacesta.si / www.city-toolbox.net) for future references and access.
