Humidity Sensor

Please login with a confirmed email address before reporting spam

Hi!!!
I am trying to design a humidity sensor, but I am facing a very basic problem- how do i set the conditions such that it indicates the natural creation of water vapor or what material do I add so that I can get water vapor. I f some one can plz help me out here...I could give further details of the project. Also which physics do you think I should include for the designing aspect!!!

Hi

considering air + moisture is a delicate (2 phase) issue, there are a few articles at the COMSOLconferences.

I tried once to get the material data of air updated to contain a moisture dependent variables, without manageing to finalise this in all generality. There should also be some new features in v4.3 too, havent managed to get to that chapter yet.

You can also find many articles in the litterature and a few books on the subject

I know thre are several team around working on moisture transport in buildings and soil, and using COMSOL but I havent seen these persons very active on the Forum,

It would be nice if these could find some time to give us some constructive hints :)

Good luck
