Oregon Scientific WMR200A
This is the link to my second weather station that I am operating at my home here in Hereford, AZ. The weather
station is a Oregon Scientific WMR200A which consist of the following:
  • Wind Sensor/Temperature & Humidity Sensor:
  • Rain Gauge:

The weather station is mounted on the southwestern section of the patio roof. It sits at an elevation of about 10
meters.  The station is wireless and communicated with the base station that is located in the living room at my
computer desk. From here it is connected to my desktop computer via a USB connection.

  • Displays Weather Forecast icons—Sunny, Partly Cloudy, Cloudy, Rainy or Snow
  • Displays current moon phase
  • Indoor and outdoor (up to 10 wireless sensors) temperature and humidity measurements
  • Measures temperature, humidity, wind chill, wind speed, wind direction, UV index (optional), barometric pressure and
  • Displays dew point, wind chill and heat index readings
  • Weather alert alarms for temperature, heat index, humidity, dew point, gust wind and rainfall rate
  • Automatically sets itself to the U.S. Atomic Clock
  • Includes 5-language software—English, Dutch, Italy, Spanish and French to store and view weather data on your PC via
    USB download
  • On-board Data Logger Function stores data with a time stamp
  • Long range transmission of 300 feet (100 meters) at 433MHz between the main unit and remote sensors
  • Main console features touch-screen controls and EL backlight
  • Low battery indicator icons for both main units and wireless sensors
  • Operating temperature range: –50°C to +70°C (–58°F to 158°F with lithium batteries)
The system utilizes the Virtual Weather Station (VWS) software which is very good for uploading data to
several other locations like Weather Bug and
Weather Underground as well as to the official weather data
collectors like NOAA and APRS/

My system updates the web pages about every 15 minutes but collects data every 60 seconds.
This weather station reports to several other websites.
