Oregon Scientific WMR200A
Overview
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.

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/
CWOP.

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