Monitoring stations in MUV

As part of the effort to promote sustainable mobility, the MUV is developing Monitoring Stations that will be deployed in each pilot city in March 2019.

The role of these stations is twofold: the first role is to measure air quality and sound levels in the pilot neighbours. Although official air quality measuring stations already exist in most of the cities, their measurements are mostly relevant in the proximity of each station’s location. Points that are important to citizens are therefore not necessarily covered by those stations, and this is where our stations can play a role.

Of course the quality of the measurements is not the same as the one of the official stations, since we use sensors that are significantly cheaper than the official ones, but the field is rapidly developing and data quality is enough to get an initial understanding of the situation. Such understanding can then be the basis for further actions from the citizens.

For air quality we are using a Dust (PM) sensor, a NO2 sensor and an O3 (ozone) sensor. As mentioned above, we also measure sound levels (in dB). The design is modular and not all sensors need to be present, for the case that a community does not have interest in measuring or using a particular sensor.



The second role is that of measuring proximity. The proximity sensor is meant to support check-ins at specific places. To perform a check-in you need to have a tag or a phone with NFC enabled, and be close to the sensor (a couple of cm).
This functionality is meant to support game dynamics in MUV, such as giving points if a MUVer visits a particular shop or goes to a social meeting point such as a library.

Our monitoring stations send data to the MUV platform, where the data is stored and can be visualised via a web page. We are also experimenting with ways to visualise air quality on the station self, in a way that is easy to understand and communicates easily the status of air or sound pollution. For this challenge we partnered with the Master Digital Design at HvA. The first prototype (as shown in the first picture) is an abstraction of lungs breathing air, with corresponding motion and lights. This prototype has been designed by four enthusiastic students, Jolijn Friederichs, Sven ten Voorde, Sofia Tsalidou and Amy Gorris. They researched, designed and developed the prototype during a six week project.

In the future we are planning to explore traffic measurements, very likely using a camera.

Exciting things to come, so stay tuned!
