Custom Enclosure
How to test an electronics enclosure to determine if water is condensing inside?
We have a custom enclosure that houses electronics. We have a humidity sensor installed and can read that via wireless. We want to know if air trapped inside the housing will condense under any circumstances. How do we test for this? We have put the housing into a freezer and then brought it out and read the sensor. Are there other tests that we can do?
You could put a glass window at the lowest point and look at that, either visually or with a beam set at a glancing angle and going to a photosensor. You could also put an glass plate in there and deposit two electrodes on the glass. Measure the current between the electrodes and it will increase dramatically with moisture in there.
