This will allow to obtain a current picture of the state of air quality and the presence of allergens in the air at intervals of time. These will take the form of a publicly available generic service that provides data and predictions to both mobile applications for end-users, as well as various specific systems such as smart houses, modern cars, medical prevention systems, etc. The main component target platforms are: wearable sensor and pollen particle sorting (world innovation), PollFree platform (this includes big data collection, automatic analysis with artificial intelligence and generic services to provide information and forecasting to external systems, and provides services for receiving data from IoT sensors and measuring devices from third-party providers), personalised information on essential air quality indicators on a micro-level.
