    Davis VP2 Console

    The Davis Vantage Pro 2 console enables the simultaneous display of many different values supplied from the Integrated Sensor Suite, additional sensor packs or from it's own internal sensors in both text and graphic formats. In addition to this it also relays information received to the Davis Weather Envoy Unit, which contains the all important data logging module.
  • Integrated Sensor Suite

    Integrated Sensor Suite

    The ISS consists of the conical black rain gauge mounted above the white louvred radiation shield, which serves to prevent temperature errors due to sunlight falling directly on the temperature sensor. This shield contains the temperature and humidity sensors but, in addition, houses the circuitry for combining the inputs from other outside sensors which are plugged into the mainboard.
  • Anemometer

    Anemometer

    The Anemometer measures both the wind speed and the direction and is of the standard 4-cup hemispherical design that has changed little since it was invented in the 15th century.

    Made to withstand strong winds but sensitive enough to pick up even the slightest breeze. A Davis Anemometer reported wind speeds of 175mph during Hurricane Andrew before the tower it was mounted on, collapsed!
  • Solar Sensor

    Solar Sensor

    The Solar Sensort measures solar radiation and is used along with an anemometer and a temperature/humidity sensor, to monitor evapotranspiration.

    The diffuser element and housing are carefully designed for accurate cosine response. Silicon photo diode provides good match to solar spectrum. Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust.
  • UV Sensor

    UV Sensor

    The UV Sensor measures the sunburning portion of the UV spectrum. It allows the console to display UV index, dose rate, and daily and accumulated dose.

    The multi-layer filter provides a spectral response that closely matches the Erythema Action Spectrum. Diffuser provides excellent cosine response. Two-piece housing minimizes radiation heating, allows convection cooling of the sensor, and prevents the trapping of water or dust.
  • Siting

    Siting

    Set on the edge of Dartmoor National Park, the ISS is mounted on a 5m alloy pole in the middle of a field with no obstructions in the vacinity. This allows for more accurate measurements and the site currently achieves a 4 star rating on the Met Office's WOW programme.

    The site also reports to PWS Weather & Weatherbug.
