Auroras - GPRS Weather Station
From Sensors
The monitoring system SAVE GRAPE integrates the weather station functions with a vineyard management software. The result: control of the climate and the vineyard conditions, and data processing on the basis of predictive models. The purpose: to support the making decision of the vine grower in order to semplify the work in the vineyard and predict diseases such as downy mildew, powdery mildew and botrytis.
