I found a good site at,  http://205.247.156.2/ they have a section on
gas sensors. Plus lots of other good info.

I am starting work on an application that requires a low cost O2
sensor, and I was thinking along the lines of trying to build a custom
paramagnetic O2 sensor. Does anyone have any experience with these?
