AiREAS expands its network of AirBoxes in Eindhoven with the monitoring of traffic emissions

Petten/Eindhoven, 15 December 2014 – Today, the network of AirBoxes used to monitor air pollution in the city of Eindhoven (Netherlands) has been expanded with NO2 sensors. As from now, nitrogen dioxide will be monitored along with particulate matter and ozone. Nitrogen dioxide is mainly emitted by traffic.

Since the end of 2013, 35 AirBoxen are installed throughout the city of Eindhoven, monitoring particulate matter of different sizes (from 10 micrometer to as small as 1 micrometer) as well as concentrations of ozone. The AirBoxes are equipped with newly developed sensors. This Innovative Air Monitoring System has been co-created by the multidisciplinary cooperation AiREAS, in which the local city government, the province of North-Brabant, enterprises like Philips, Imagelabonline and Imtech ICT, the universities of Utrecht and Twente, the Academic Medical Centre and Energy research Centre of the Netherlands (ECN) participate, among others. ECN has been responsible for the development of the sensors. The development of a cost effective and reliable NO2 sensor has been a challenge, but ECN managed to create a sensor that performs well. This NO2-sensor is now installed in 5 AirBoxes across the city.

Towards a healthy city
AiREAS wants to co-create a healthy city involving citizens and institutions. For that goal, it is important to know exactly which concentrations of pollution occur in which locations. “The Netherlands performs quite well in achieving the norms for air quality. At a national level we  comply, although we do have some local problems. But the purpose of AiREAS is to look beyond norms and create a healthy city. For this purpose, the situation needs to be looked at with much more precision”, ECN air quaity expert Ernie Weijers explains. “Now that we can monitor these three components, we have a network that provides us with excellent local insight.”

With the information the local governments can take measures and do research on health effects, or improve the traffic management. The data are publically available via, allowing civilians and forms to also contribute to the improvement of their living space.

According to Weijers, other cities can benefit from the experiences in Eindhoven. “The interest in other communities is large and we expect to expand to other cities soon.”
