Dust sensor on raspberry pi

Got my Grove dust sensor working on the rapsberry pi, directly connected to the GPIO with 2 resistors(3k and 2k): https://github.com/otonchev/grove_dust
Works pretty well, gives very similar results to a setup with the Arduino Uno and digital input 8

Hey ogy_tonchev,
Thanks a lot for letting us know about the alternate option to use the dust sensor.
