<html><body> AntiPollen: The Barcelona Shield Real-time, hyper-local pollen detection (sneeze-free) Inspiration This year's Sant Jordi was a near death experience; pollen was the absolute protagonist. So, we decided to build a shield for the citizens of Barcelona. What it does AntiPollen is a real-time, hyper-local pollen detecting mesh designed to keep your respiratory system (and your sanity) intact. By identifying hot pollen zones, the users can avoid them as well as itchy eyes. ow we built it Hardware: An Arduino mesh network deployed across key urban points. Brain: Each node runs a custom Edge AI model that analyses local particulate matter to distinguish between general dust and specific pollen concentrations. Interface: An intelligent dashboard that aggregates this distributed data into a heatmap. Challenges we ran into We couldn't get the vibro sensor, so, to mesure the wind, we had to rely on public APIs to provide that data for us! Accomplishments that we're proud of Our amazing ML model that we trained ourselves by getting and cathegorizing our own images of pollen. What we learned The Arduino is much more powerful than we anticipated, we learned a lot about how sensors and the Arduino ecosystem works. What's next for AntiPollen We are looking to scale our mesh to the most congested areas of Barcelona and integrate our API into popular navigation maps to offer allergy-friendly routing. </body></html>
