@peekay123,

great to remind me that the power for the Grove Air Quality is 5V an also the issue of the 10 bits vs 12 bits to handle…

On the other hand, after deep digging, I finally found that the AS-MLV seems to be also used in the EveryAware SensorBox project, and I found also an Arduino integration of the sensor by Dirk K. (dekoepi): [http://www.heise.de/make/artikel/Wider-dem-Mief-2235138.html](http://www.heise.de/make/artikel/Wider-dem-Mief-2235138.html) and [http://www.mikrocontroller.net/topic/336431](http://www.mikrocontroller.net/topic/336431)  
and the related code in C… for Arduino: [http://pastebin.com/4YeBrv9h](http://pastebin.com/4YeBrv9h)  
and for ATMega 328: [http://pastebin.com/RVVtzSSh](http://pastebin.com/RVVtzSSh)
