The concept

The Captothèque is a platform that allows every citizen of the Auvergne-Rhône-Alpes region to borrow a micro-sensor for measuring air quality, without any condition of resources. This will allow each citizen to freely measure and understand the quality of the air they breathe on their territory.


The citizen, at the heart of improving air quality

Air quality is an important issue in our territories and each of us, as citizens, through our choices of consumption and activities, have an influence on the quality of the air we breathe. Thus, the citizen is at the heart of improving air quality. It should therefore logically have the power of knowledge and action on the subject.


Bringing citizens together and air quality monitoring

While the citizen is at the heart of the solution, he or she is not at the centre of the traditional air quality monitoring ecosystem on our territories. Information and knowledge about pollution in our territories are not necessarily disseminated in an optimal way, and above all do not benefit from the increased observation of the populations that breathe it. So we want to open a new way: since the citizen is the solution, why shouldn't we put the solution at the centre of the surveillance system?


Micro-sensors to better understand our air

To succeed, we had to find the best way to bring together, raise awareness and exchange locally about air quality. The Mobicit'air experiment, conducted by Atmo Auvergne-Rhône-Alpes and supported by the Auvergne-Rhône-Alpes Region and the Grenoble metropolis, showed that the micro-sensors for measuring air quality used in a citizen participation approach fulfilled these objectives.

Widely deployed, micro-sensors could provide the monitoring system with large volumes of data at finer spatial and temporal scales, particularly in territories that are currently without tools. But beyond the technique, citizen experimentation and individual measurement of air quality allows everyone to freely define their own measurement strategy, to better understand and apprehend the different local phenomena.


Equitably equip citizens and territories

Thus, in response to these results and the interest of local communities in the subject of individual air quality measurement, Atmo Auvergne-Rhône-Alpes decided to launch the Captothèque. This service allows everyone to borrow a micro-sensor for air quality measurement free of charge and use it freely. The data collected can be viewed and shared with the community. In some areas, support is offered to invite citizens to measure specific pollution phenomena.

By offering this service, our ambition is to place concerned citizens at the centre of air quality monitoring to democratize and expand local air initiatives and knowledge.
