Hi!
I'm using MQ-2 sensor for arduino, and how can i detect smoke only, not all inflammable gases?
I'm using example sketch of MQ-2 Library.

Hi,

The MQ-X series are Taguchi Gas Sensors and their surfaces respond to different chemical substances.

If you want only "Smoke"  or "unclear air" you will need an optical transmission type sensor, I believe.

See THIS google search (Which you mighta done yourself)..

Aren't smoke sensors already fairly common devices?  I can see three right now from where I am sitting in this hotel suite.

Please do not PM with technical questions or comments.  Keep Arduino stuff out on the boards where it belongs.
