    Ive built a kit CO sensor as you describe & it cost a bout $70. I later purchased one on E bay for $35, which can be altered to run of 12V DC. I use this in my caravan. Pics of the Ebay unit i finished up using.

    You would need to buy the Kit as the PIC is pre programed. Whynot buy the Ebay one as its half the price & does the same job?

    that sounds like a good idea....any links as to where i can get a kit and use my own pic and programme it. i would like to get a bit more hands on and understand how the circuitry actually works
