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)

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)
- Those sensors are already used by http://fridav.ljudmila.org (that's how we
found them)
- Based on a Fonera which could connect to the /tmp/lab wireless network and
directly post results on the internet
- Using SPI with Fonera: http://www.larsen-b.com/Article/262.htm
- ADC: LTC2496 (I can bring an evaluation kit)
- My LTC2496 driver for Linux: http://lekernel.net/ltc2496
