Condensation occurs at sub-ambient temps. Ambient temp = ~room temp. That is basic but reasonably accurate.

Dew point
P.S Good luck, be interested to see if what you build works.
thanks for the links Mr. Smith.
ive read through them and im still gonna try the test coz im curios

i have a digital temp monitor kicking around so it wont be too much hassle to test.
i know that the dew point and condensation forming are dynamic so my test is more out of curiosity .
