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

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.

I also have an Oregon Scientific wireless WS (WMR968) and it will do what
you want but as Ray said, there are limitations you should consider. The
range is a real key issue. In my one level home with a brick exterior, I
often lose contact with some of my 4 external remote sensors, one on the
enclosed patio and 3 on the deck railing. If I move the console into my
office and hook it up to the computer to track weather changes, I'm unable
to reliably stay in touch with the sensors.

A friend with an identical system worked with tech support trying to get his
to be more reliable but he finally gave up.

Davis has repeaters that work with their remotes but I haven't looked at
their products.

I've been looking for a Wi-Fi weather station but apparently they're not on
the horizon.

None of them are cheap either.

Good luck.

Jim
