These questions come up regularly. It is much much much easier to average
it in software after the fact, then you can apply the filtering you want or
try different ones.
Look at this temperature graph (it takes a while to load, there is a lot of
data) (yes, it may even take longer than that):

Better still, but more potential to be messy. Another advantage is that
there's no need to waterproof the sensor. I was thinking along the lines
of sticking the wire through a small hole in
Averaging in software is preferable for temperature measurement.
If you shield a sensor from air currents you leave it far more
sensitive to radiation errors and errors from conduction along the leads.
These problems only increase if you try to place a brick on the sensor to
average the response,
Seems inflation has done its job

well, are you sure that includes the bracket and so? I think I paid more than
that about 1+ years ago.

I want to setup an experiment where I log both voltage and
temperature. I will be using DS18S20 sensors. I would like to shield
the sensors from direct air currents due to AC and heating system.
I'm thinking perhaps something simple, like a pill bottle drilled with
holes to minimize the effects of
NIST is working on a quantum thermometer. Apparently the current version is
not very accurate, but they are working on it. If it ever comes to be,
should be interesting... particularly when paired with their photonic
thermometers.http://www.nist.gov/pml/div684/nist-creates-fundamentally-acc
You should use oil so that you do not get evaporative cooling. I have
worked with temp rules that talk about oil filled 1 quart jars spaced
around the point you want to measure.
