I was confused with the results because I wasn't expecting such high values from the 4th test where i just had some dust falling from my rug. Ok, i admit my rug hasn't been washed for a while but the voltage should only go up when the density is high, and compared to smoke, dust wasn't dense at all.

0.6 mg/m3 of dust doesn't seem much when National Institute for Occupational Safety and Health (NIOSH)'s recommended wood dust is 1 mg/m3 and used to be 5mg/m3 for softwoods.

!Setup and Code
Setup is very straight-forward except the soldering. 6 pin connector header is small and very closed. I had to break one side of the header housing. \\
One important thing about the code is in order to turn the ILED on, you have to digitalWrite LOW on LED input terminal. Because the transistor that opens the drain is PNP type of transistor which needs negative base voltage.\\
I also added a buzzer which goes off when it detects smoke.
