Artificial nose? Helping industry trace their leaks? MRTG for toxic gas?

Welcome to the wonderful world of post-chemistry.

Sniffing

  • Carbon Monoxide (CO), Hydrogen (H)
  • Hydrogen (H), Ethanol (C2H6O), Iso-butane (CH3CH(CH3)2), Carbon Monoxide (CO), Methane (CH4)
  • Toluene (C7H8), Hydrogen Sulfide (H2S), Ethanol (C2H6O), Ammonia (NH3), Hydrogen (H)
  • Ethanol (C2H6O), Hydrogen (H), Iso-butane (CH3CH(CH3)2), Carbon Monoxide (CO), Methane (CH4)

Using

Proposal

  • Sensors: cheap sensors made by a company called Figaro - one TGS2600 + one

TGS2602. Available at Radiospares for roughly 30 Euro both (but I had bad experiences with them) and maybe Diltronic (someone should call)

found them)

  • Based on a Fonera which could connect to the /tmp/lab wireless network and

directly post results on the internet
