Project SensorWeb PM2.5 Pilot Website

Project SensorWeb is a crowdsourcing sensor network.
We believe that open data can help revealing significant residential information and making lives better.

PM2.5 pilot website provides simple ways for users to discover relevant air quality data and contribute to the network.

This website is still in early beta,
