Humidity Sensors

I have a requirement to place 4 humidity sensors in and around my home. The sensors are to be placed in 2 bathrooms that have showers for humidity control of the fans (via X10) as well as one placed on the main floor by the thermostat and one outside.

I am using this device

for temperature measurement and I am looking for something similar for humidity. If you know where I can get something like this device or something similar I would like to know.

TIA, Eric

Here's an application note on how to make a "1-wire" humidity sensor using a Honeywell humidity sensor and the DS2438 Smart Battery Monitor.

A widely used digital output humidity sensor is made by Sensiron

The Honeywell HH-3605 and HH-4000 series have analog output.

Peter Anderson offers kits suitable for both.

Also google this newsgroup. It is a PAQ.

The url is correct but note that the second"i" in Sensirion.

I can recommend even the older HH-3605. The newer HH-4000 series would appear to be an improvement.
