Grove Dust sensor and Raspberry Pi

Ordered the sensor some weeks ago and yesterday I managed to get it working pretty well on my Raspberry Pi, results are very similar to a setup where the sensor is directly connected to the N8 digital input on Arduino Uno.
Some more info about my setup is available on my github site(github/otonchev), just search for Grove Dust sensor and Raspberry Pi on github
There is also a link to a live data chart of Fine particle (PM2.5) in Lund, Sweden.
As soon as my newly ordered sensor arrives I will be publishing a link with Live data from Sofia, Bulgaria. The air there is slightly more polluted and it will be very interesting to compare AQI with live data from aqicn.
