A total of ten air quality sensors are available for loan at Itäkeskus, Vallila and Viikki libraries and Central Library Oodi. The air quality sensors measure the carbon monoxide content of outdoor air, and the results of the measurements can be viewed on a downloadable smart phone application.
The air quality sensors are intended to be carried on the wrist using the attached wrist strap. The sensor transmits data to the user’s phone via Bluetooth, where it can be viewed using the Oo application developed by geme.io. The measurement data is also transmitted to the University of Helsinki, where it is used for research purposes. As the data accumulates, the results can also be viewed by anyone on the geme.io website and on information boards in the libraries that loan out the sensors.
