At our acreage site near Miquelon Lake I have installed a Peet Brothers weather station. It's original purpose was to keep a trend of the average wind speeds at the site. Knowledge of this information was needed because I intend on powering our future home using multiple wind turbines.
The weather station's anemometer is located at the 35 foot level of the tower. Weather data is transmitted via an APRS radio link (every 10 minutes) to the internet gateway of VE6BCA. Current weather data being sent is wind direction, current wind speed, one minute average wind speed, temperature, and 24 hour rain fall.
