Doug, Whereas indoor humidity is what interests you, what is happening outdoors is what can influence it, with a time delay. I'd seriously suggest you have a data-logging weather station with indoor humidity/temperature sensors situated at working station level, but not close to actual stations to avoid human interference. For many years I have been following outdoor/indoor conditions. with a Davis weather station and I can see the influence wind, sun. outdoor temperature and humidity and rain have on indoor conditions. I use these data to decide how to set heating/air conditioning levels for comfort and economy in the home a few hours in advance of changing weather conditions. You may wish to take a look at http://www.davisnet.com/weather/products/index.asp for the hardware. For the software, I use a more sophisticated one than the Davis one at http://www.weather-display.com/ and for accurate forecasting you can use http://www.wxsim.com/ Brian On 29/11/2012 21:16, Douglas Pauls wrote: > Good afternoon everyone, > > I would like to know if any of you have, in your facilities, wireless > humidity sensors that connect into a master data (digital) recorder?
