This may be too long for you to wait, but the following device is
supposed to be available in April:
http://www.ibutton.com/weather/humidity.html
It looks like it'll be pretty slick--RH, temp, light measurements in
one pkg.
More info on 1-Wire weather devices and other humidity sensor
options currently available:

I will be working on after the holidays?
I've done an internet search and came up blank.
Thanks

take your search to http://www.google.com and STAND BACK. It's fast
and quite thorough.
I just got beau coup hits on the two words 'humidity sensor'.
good luck
(I don't have a specific recommendation, but when we were ripping
apart some old microwave ovens, we came across one that HAD a
humidity sensor in it. (a four terminal bridge sensor)

There are many others, some of them cheaper, but I have

You may want to wait for others' responses, there may be a cheaper
alternative.

Here is a link to the sensors page at Honeywell/Microswitch.
http://content.honeywell.com/sensing/products/sensors/
This includes the HIH3605, the new HIH3610, and the premium HIH3602.
These are available from
http://www.newark.com/
and from some other Honeywell distributors like Steven Engineering.
Be sure to pay attention to the data sheet, about light sensitivity.
The Vernier RH probe uses the HIH3602L, and comes in a nice package:
http://www.vernier.com/probes/rh.html
I use the premium HIH3602C in my humidity sensors, which include a
built-in RTD for temperature compensation and dew point calculation:
http://www.emesystems.com/RHTD_DAT.HTM
Here is another one that might be of interest to you. I think this
is the one that Matt Parnell uses in the weatherstamp station:

the small ceramic sensor, normally glued in a small steel plate. The
sensor itself is a plate about 1/4" x1/4" with two wires . It changes
resistance.
I don't know nothing about sensivity and linearity.

This is a different Paul. You can order them from Newark. Also try
contacting Honeywell. You can order samples.
Paul, not the first, just a different one
Does anyone know a humidity sensor for atmosphere use to measure RH
with a BS2

Hola Roberto,
Basic sensor elements are based on either resistance or capacitance
transduction, and require a circuit like the 555 timer (Mediciones
Ambientales, chapter 5) to provide AC excitation or transduction to
frequency that can be read by the Stamp.
There are also sensors that output a voltage directly that can be
read by an analog to digital converter.
What environment will the sensor be exposed to, and what accuracy do
you require? That is the big question with humidity sensors. The
cost is related to the accuracy, range, environmental compatibility,
and longevity.

I want to thank to all for the help gave me with the humidity
sensor. It has been of a lot of utility.

from
radiosondes. Electronic Goldmine used to carry these, but if you check
around different surplus places, you might have some luck. These are not as
rugged as you might think, but they are very easy to read.

hmm, good source for such things, Any words on how quickly
they respond? These are 'disposable' radiosondes aren't they. Will
they 'wear' well undercover but outside? Will the humidity sensors in
electric clothes dryers work also? THESE sensors have been known to
get flaky. Maybe when coated with antistatic goop?

looking for an accurate sensor to monitor humidity levels in an
incubator for reptile eggs. I would like to find one that is easily
connected to a BSII. Any suggestions???
Stampboi
monitor the humidity in a reptile incubator. The sensor should be
accurate, and easily attached to a BSII.
Any Ideas???
Stampboi
easily wired to a BSII.
Any suggestions?

1) The Honeywell/MicroSwitch sensors are used with an analog to
digital converter:
http://content.honeywell.com/sensing/prodinfo/humiditymoisture/
http://www.emesystems.com/rhtd_dat.htm
The can be obtained with good calibration data, and the second
reference has information on using them with the BS2.
2) General Eastern has several different humidity products, optimized
for different environments:
http://www.geinet.com/html/HumidityTop.asp
3) Panametrics Minicap II capacitive sensor can be used in 555
circuit to give period proportional to humidity.

I have used Vaisala units to monitor humidity for years. Very good units, but I
have not tried interfacing them
with stamp yet.
Here is the URL on them.
