Hi all,
The SensorWeb’s first PM2.5 air quality station is working now. You can check http://goo.gl/XdgkTg to see the real-time PM2.5 data in Mozilla Taipei.
It is the station, built by Arduino-like board and LEGO.
The more detail is in the blog post http://goo.gl/BhkuVr.
If you would like to understand PM2.5 more deeply, you can check the air quality guidelines http://goo.gl/eFgnvC published by World Health Organization.
And You can also check our source code in https://github.com/sensor-web, and file bugs in the Connected Devices/Project Sensor Web component in Bugzilla for our stability.
Thanks.
