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)..
Hmm, i saw that and my next question is can i create smoke sensor with obstacle detector?
how can i detect smoke only,
Use a smoke detector.
