The Oregon Scientific WMR200 Professional Weather Center provides comprehensive weather data direct from your own back yard!

The WMR200 Weather Center comes complete with all of the sensors shown above, a solar panel that supplies additional power to the thermometer/ hygrometer and anemometer, and various mounting poles and hardware, attachment brackets, and sensor and solar panel connectors.

The WMR200 touch-screen interface features a radio-controlled (atomic) clock and displays current indoor and outdoor temperature and humidity, wind speed (current, gusts, average) and direction, wind chill, dew point, heat index, barometric pressure and rainfall (rain rate, hourly rainfall, accumulated rainfall and 24 hour rainfall). For additional weather monitoring, the WMR200 can support up to ten remote temperature/humidity sensors (including an optional UV sensor). Icons show the weather forecast for the next 12-24 hours within a 19 to 31 mile radius.

The WMR200 memory allows you to view the minimum and maximum temperature, heat index, humidity, dew point, wind speed and wind chill. View hourly records for the barometer, rainfall and optional UV data. The WMR200 also features an onboard Data Logger that stores data with a time stamp at user-selectable intervals, which can then be uploaded to your PC.

Note: We do carry a magnetic compass to help you orient your anemometer to true north. For more information on set up, please visit the anemometer page on our WeatherShack education center.

I had not problems setting up the WMR200. Everything is working fine so I would give this product a very high rating. My only problem is that I did no know that the sensors were all battery-operated. The only place I have to mount the sensors is on my TV antenna mast which will mean climbing 20 feet or so to the roof of my house to replace batteries. I do not know how long the batteries will last or how much the small solar panel can support the sensors. Replacing batteries, especially in the middle of winter in PA may be a major problem. It would be nice if individual weather-protected power supplies could remove the need for periodic battery replacement.

Hi --- I was very favorably impressed with the WMR200, with a few minor caveats. The first is that the UV sensor fails to feed data to the console and the "wind chill" area remains blank. The measured rainfall reverts to "0.00" long before a given rain event has ended also, which is a bit of a frustration.
