co2 carbon monoxide alarm, silicon chip kit

Sep 21, 2006 6 Replies

Has anyone built that CO2 alarm kit features in 2005 Silicon chip. I see DSE selling kits for $49.95. I dont have the article and I cant see what sensor it uses online from siliconchip homepage. Can someone tell me the part number of the sensor so I can look up some date on it. I want to connect it to a data logger to measure ppm. Not sure if sensor good enough. I want to log Sydney CO2 levels, maybe on the Sydney bypass!



Isn't CO2 carbon dioxide, and CO carbon monoxide? I'm confused.

oops my mistake - yes co detector

Thanks for the clarification. :-)

Apparently the Silicon Chip design uses a Nemoto sensor. I don't presently have access to my copy of the magazine to see exactly which one.

The Nemoto website has quite a lot of info, so check it out at

Good luck!

Don't those sensors have a fixed shelf life?, probably the DSE units are tired by now.

thanks for the tip, you are right, a two year shelf life is correct. Probably why DSE is discounting.

I was told there are newer Sn02 based CO sensors used in professional CO meters.

cheers!
