Is there a sensor to measure the degree of humbleness a human .......

Actually , I have question about capacitive humidity sensors.  I was told t=
hat they typically measure relative humidity ( RH ).  I don't get that.  Wh=
y would they not measure AH ( absolute humidity ) ... that is .... the amou=
nt of moisture per volume of air ( grams per cubic meter ).  Or does the ca=
pacitor accept water contingent on the temperature ?   My visualization was=
 two giant capacitor plates with air circulating between them.  The amount =
of water in the air would change the capacitance.  Then I started thinking =
about the fact that temperature would affect the density of the gases in th=
e air.  Would that affect the amount of moisture per volume of air ?  Then =
my brain exploded.
