Wow, Paul, what a list! Thank you so much! I've bought from the "pcsensor"
guys before (and sheepwalk) so I'll probably get the < $20 one there. Thanks
very much!

This one fits into a standard UK electrical box and works well

Hey all!
Does anyone have a source for cheap 1-wire humidity sensors?

The DS2438-based humidity sensors (family code 26) use the DS2438 chip for
temperature and voltage readings and a separate humidity chip like the
HIH-4021.
The humidity reading depends on the actual temperature and the voltages
read from the chip. Different generations of humidity chips have a

Yes I figured it out. A web page I saw misled me into believing that was
the correct device. Me bad.
What's the difference between HIH4000 & HIH 3600, they both have a
humidity field. Their numbers are a little different though.

I asked the same question a while back. The answer from Eric Vickery,
the Hobbyboards guy was
'You should use the HIH4000 for the humidity readings. The sensor used
on our humidity boards is the HIH-4021 now.' I believe that the others
are to allow for different sensor chips to be used, maybe
My Hobby Boards humidity sensor works. The data is at:
1F.A5D20300/main/26.D89C2101/HIH3600/humidity
I am a rookie at owfs as well so don't understand the construct of the
addresses.

Wrong device. The Humidity sensor is 26.F59F2101. The software
setup allows for several actual sensor modules, the one in my
Hobbyboards unit is an HIH4000. The directory layout is a bit different
to temperature sensors, under the 26.F59F2101 directory there is an
HIH4000 directory a
I am having trouble getting owfs to read the humidity sensor. I have

I believe it's been supported since 2006. See

So the same circuit, just just different calibration.

i don't know why but honneywell here in brasil is about 100% more
expensive than another country :/

Aagelectronica sells a humidity sensor for $44, and Hobbyboards for $48.
Also, the humirel part might be cheaper, and is supported.
Still, if you build a circuit for the HS15p, we'll try to support it.

I've used the HS15P before on a PIC. It's not going to be easy to interface to
1 wire. The big requirement is that the sensor can *not* have a standing DC
voltage across it, or you will destroy the sensor. As it says in the datasheet:
AC voltage 50 Hz to 1kHz. You may be able to place this acro
it's like HIH from honneywell but it's an variable resistor and you need
temperature compensation, and an AC1V 1KHz source to get long life to sensor
i'm trying to construct one and use an ow that have 2.4v - 10v input and
corrent input too and temperature too :)

Interesting sensor. Is it part of a 1-wire circuit, or were you going yo try
to construct one?
The give "Typical response curves" -- but we'd need to do some curvefitting
to make a formula.
