Outdoor wireless thermometers

Dear PBS List,
We have an old Davis Instruments system installed here more than 20 years ago and it's been flawless.  It doesn't have the rain gauge that automatically empties nor does it have computer interface but these are available as well as many other features.  It does have an anemometer and temps are reliable, we feel, when compared to the remotes that sense temps on the three Oregon Scientific ones we have placed in various microclimates.
The Oregon Scientific remote thermometers are available very cheaply now at places in the US like Lowe's, Target, etc.  And they are getting better inasmuch as they can record data from further away than 100 feet.  We've had them for 10 years and also more recently.  They take the heat here without incident.  We mark the batteries in them with permanent markers so that when one fails, we can check when they were installed.  Batteries, so far, are always the cause and not instrument failure.  
At Boyce Thompson Arboretum, we have Robo sensors that collect and deliver data from numerous location every five minutes to a newer version of the Davis system and that data is obviously downloaded and recorded.  Very important for a public garden.
The most high-tech sensors anywhere are probably at The Hungtinton Botanical Garden where sensors were donated to them a number of years ago by the Jet Propulsion Labs....see the website for more information but they may not be the most currently high-tech anymore.
Best wishes,
