Electronic gas sensor
« on: September 08, 2011, 11:49:15 AM »
Hello everyone,
I've been helping a friend with some very low budget project,
I was wondering if anyone familiar with a good low budget carbon dioxide gas sensors(I know the MG811, but I was wondering if there is anything with similar quality availible for under 20$, or maybe even (may I be too optimistic) under 10$) ?

Thank you very much,
A.

If you type "gas sensor" into a google search bar it shows a number of possibilities. Pololu has one for about $6

Joe, thank you for the response.
Please notice I need a specific gas sensor, a CO2(carbon dioxide) sensor,
I searched pololu site and didn't find that specific gas sensor,
If I missed it, please direct me to it.

Thank you,
A.

Ah, that's a carbon monoxide sensor, sorry. In that case type in "co2 sensor". There's one at Futurelec, and some other hits as well.

Thank you,
I see Futurelec sell the sensor for 19.90$,
we need something cheaper.
(I think I missed the other hits, can you please point them to me)

I've never used one, all I know about them is what's available on the Google search results. There were datasheets on a couple other products, but I didn't see any prices.
