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)

Proposal
Project completed! http://lekernel.net/blog/?p=509
- Sensors: cheap sensors made by a company called Figaro - one TGS2600 + one TGS2602. Available at Radiospares and Diltronic (St Germain en Laye)
- 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.html
- ADC: LTC2496 (lekernel: I have an evaluation kit)
- My LTC2496 driver for Linux (lekernel)
- A DCF sensor may be integrated to the sensor system as informations sent to the server will arrive in random order.
