Ambient Statistics temperature/humidity/barometer

What are you all using?

On the Barometer. Wouldn't the pressure be rather constant for 10s of acres? So then you would only need a base station with that feature.
FWIW, I've toyed with buying a full weather station (add in wind speed/direction and rainfall a few times...and then bought other toys.

A full weather station is beyond my interests as well. I just need something to tell if the observatory has cooled and the potential for dew. Predicting when I should close the roof could be done the old fashioned way; look it up in the paper :-)

Something I found really cool for night time cloud detection is a "Dome Camera". Point it up and some of these will see to 5-6 mag with a 3MM Lens. As I'm more Orange zone (sadly) wispy clouds are visible, and when the Stars start blinking, good time to close up. As the unit is "Weather resistant" you just leave it set up. 12V power and an analog video feed is all it takes.
Going further into geekdom, I have a TV tuner in the Obs computer with an analog connection the camera feeds into. Avermedia G2 is a good tuner kit for this.
EDIT: Googled around and saw the G2 is hard to find at circa $80 pricepoint. Another tuner card (with Analog input)that I have used is the Hauppauge 2250.
After that you're looking at multi input DVR cards

Our equipment is owned by WeatherCurrents, although I invited them to install the station when we moved here. The equipment is all Peet Bros, plus a custom-built computer to store the readings in case my ISP goes down or there's a power outage. In addition to the WeatherCurrents website, I've also found our data on a site called Mesonet West.
I'm using a Davis Vantage Pro 2 Plus with a 24/7 fan aspirated radiation shield. It reports to both a weather console and a separate Weather Envoy with a data logger that logs serial data via a serial to USB cable (more reliable than a USB data logger) to an instance of Meteohub running in a virtual machine on an ESXi host. Meteohub then forwards the data on to about eight other weather networks some of which re-forward the data to yet more weather networks.

@tom and beth, I think nearly everyone on this board qualifies as a Geek! Especially those Model Train guys! Man! There are some wild collections out there :-)
@OJS, those Ambient Weather stations are the most attractive ones so far; big number, multiple senders/single station, inexpensive; looks good to me!
except it's blah... out of stock...time to shop around! Cool Amazon has a three sensor version. Nab!

That's way cool, a free weather station just for the asking.
Our equipment is owned by WeatherCurrents, although I invited them to install the station when we moved here.
They're incestuous. Or rather it all becomes public data and anyone can bulk feed from that trough. I certainly don't mind. The data I send to CWOP apparently also finds its way to NWS and Mesonet.
I've also found our data on a site called Mesonet West.
Anyone thinking of purchasing a weather station, don't pay MSRP or MAP. Ask for the dealers actual selling price. It'll be much lower and you'll save money.

I'd love to hear and see how you did it with Arduino. I'm looking at an Arduino
board sitting on the table in front of me right now, waiting for parts and anxious to give it a go.

I was thinking of getting something like this for my observatory:
I picked a set of these with three total remotes. nice big numbers ;-)
You can get as many sensors as you want. Unfortunately, most seem to be out of stock right now.
