Sensor for cigar and cigarretes

HI All,

I am a rookie in the electronic world. I would like to build a cigar (cigarette) smoke detector, nevertheless, I do not know what smoke detector should I use. I just reviewed the MQ-7, MQ309A and others. So, could you recommend me a cigar(cigarette) smoke detector?

Thanks

Hi rookieven,

Those look like carbon monoxide detectors. I'm not sure if they'll be sensitive enough to detect cigarettes.

Did you look for smoke sensors? Check this out: playground.arduino.cc/Main/MQGasSensors

Hi Patduino,

Thanks for the link. Nevertheless, which one of the different corbon monoxide smoke detectors should I use between the MQ-7, MQ-9, MQ307A, MQ309A, ans AQ7? According to the page you suggested all of them detect carbon monoxide.

Thanks Patduino.
