I am using an Oregon Scientific Weather station that is 'wireless' and
allows for up to 3 additional remote sensors.

Draw backs a

1) you must use VWS (Virtual Weather Station) Softeware and
2) if you are 'recording' the data, the computer must remain on.
3) range can be a factor I have mine about 50 feet from the sensors.

As far as I know, both temperature and humidity can be monitored by each
remote at the same time. I know the outdoor sensor does both. If the remote
channels are as accomodating, they should do the same.

If you are so inclinded ... look at my web page. VWS did all the graphics.

I was using a PeetBros 2000 until lightning decided otherwise.

Hi,
I have a project where I need to set up a weather monitoring station
in multiple greenhouses and have the temperature and humidity
monitored on a central computer. Does anyone have any suggestions of
how to do this?

thanks,
Sam
