who can launch a campaign


air quality sensing technologies

which type of sensors or methodes are used to obtain air quality measurements. “Direct” methods refer to devoted sensing devices bought and used by the costumer, “indirect” methods to data collection methods from offial air quality networks

data collection form official stations, no sensing unit

other sensing technologies

for example meteorological data, positioning data, …


quantitative: what kind of data is measured

speed, distance, noise, location,…

air quality data (AQI), meteo

what type of qualitative data is gathered


what kind of data is calculated

CO², cost, health, … / What is the basis of calculation (e.g. reference database, European guidelines for external costs, etc.)

air quality index (automated update every 30 minutes)

reporting method

which reporting method is used (for example: website or directly on the smartphone’s app, heat maps, dashboard, and/or reports)

smartphone appl


method of reporting (visualisation) of the collected data (qualitative representation can be a red or a green light, a text explaining the progress, while quantitative representation consists of numbers or statistics

timeseries of air quality index, evaluation on scale (good, moderate, unhealthy for sensitive groups, unhealty, very unhealty, hazardous)


self-monitoring, gamification, rewards, social networks,…

self-monitoring: obtain info about outdoor air quality in your neaghbourhood, (preliminar) exposure assessment

applicability of results

are the results useable for policy-makers and how can they obtain this information?

yes, data from official monitoring stations are used for policy. Unknown whether additional data from usage of the application is obtained and further used for policy,


gaps and limitations of the campaign or application
