Topic: Looking for O2 Sensor for Incubator (Read 1 time) previous topic - next topic

I'm looking for an O2 sensor that can function properly in a cell culture incubator (37 C, high humidity). I would also like to be able to use it for O2 readings inside of mice cages. Does anyone know where I can find one that is affordable that will also work with the arduino? Thanks

Alas the relatively easy to obtain lambda sensors used for oxygen measuring in car engine control applications only work at very high temperatures...  There are ppO2 sensors used by divers apparently, but I know little about them.  For the mice cages wouldn't a CO2 sensor be a better method?

i like the NDIR method (it works fine for CO2)...

its a good fire detector 2...

it seems like it doesnt work so good with O2...
but it should be possible to do it at 760nm according to german wikipedia:
