Weather station hardware

This website is based on a Davis Vantage Pro 2 weather station, currently about two years old.  It has sensors for the following:

  • Outdoor temperature
  • Outdoor humidity
  • Barometric pressure
  • Rain gauge
  • Wind speed (anemometer)
  • Wind direction
  • Indoor temperature and humidity

The data from these sensors is displayed on a console which is connected to a PC for processing.


The PC is running "Weather Display" software under Windows.  This is probably the most common software among amateurs, very flexible but it can be very tricky and frustrating to set up!  From the basic weather data the following additional measurements are derived:

  • Rate of temperature change
  • Rate of change of pressure
  • Wind chill
  • Dew point
  • Wet bulb temperature
  • Maximum wind gust today and last hour
  • Max and min temperature
  • Rainfall last hour, today, month to date and year to date.
  • Rainfall rate in mm/hour

Weather Display also generates a number of graphs.  Note that data is uploaded to the Internet every 5 minutes.

Data is also uploaded to the "Weather Underground" with the station ID of ISHERB47 - you can view it on a web browser or using a free app on your phone or tablet.

Location of sensors

The tenperature, humidity, barometer and rain sensors are mounted in one unit, the thermometer being protected by a radiation shield.  These sensors are mounted about 1 metre above grass.  The anemometer is mounted on a long pole about 4.5m above the ground.

The station is located at 51º0'04"N and 2º31'24"W.  It is at an elevation of about 100m.

Starting conditions

The station has been running since 9th March 2022 here in Corton Denham.  I decided to set the annual rainfall to zero as I had no other meaningful information, so this year's total will be low unless I can find some figures for January and February.
