The Davis Solar Radiation Sensor is a silicon photo diode instrument for the Vantage Pro and Vantage Pro2.
Solar radiation on its own is a niche measurement, but combined with an anemometer and a temperature sensor it is what lets a station calculate evapotranspiration. That figure drives irrigation scheduling, telling a grower how much water the crop and soil actually lost rather than how much rain fell.
A silicon photo diode responds fast and linearly across the solar spectrum, which is what makes the calculation reliable rather than approximate. It is already included with Vantage Pro Plus and Vantage Pro2 Plus, so this is the sensor to add to a standard station rather than a Plus one. Explore more outdoor optics and navigation.
