Davis Vantage Pro 2 is a multifunctional meteorological complex, designed for professional use, and has a weather function that takes into account the coordinates of the location of the complex, time of year, current atmospheric pressure and its variation, speed and direction of wind, air temperature and humidity, precipitation.
This weather station measures such indicators as atmospheric pressure, outdoor and room air temperature, outdoor and room relative humidity, wind speed and direction, dew point temperature, precipitation amount and intensity, shows the weather forecast, moon phase, sunrise and sunset time, "imaginary" temperature and wind's "coolness".
