Hello List!

Today we talked once more about a IKEA hack for Air Quality measurement.

IKEA has this VINDRIKTNING Air Sensor for roughly 10 Euros which 
meassures particles in Category PM 2.5
Inside is a sensor called PM1006 from Cubic [0] which seems to fit the 
particle size which is important for our chip manufacturing inside clean 
And, this sensor is already hacked :-) [1]

If you like to get some hardware porn - at github you'll find a source 
how to mod and expand VINDRIKTNING [2]. I guess this is a nice starting 
point for our hack.

Beside thas, IKEA also offers a particle filter with same spare parts as 

I hope I can get into the details and evaluate the usage for our clean 
room manufacturing..
Well, as David mentioned, IKEA is known for changing the articles they 
are selling quite often. This can mean that next season VINDRIKTNING and 
FÖRNUFTIG are not available anymore. But I guess, both have a longer 
live if they become a best seller ;-)

BTW, if you do not know, what category PM 2.5 means - this site [3] 

Have a nice week!
