A wireless sensor network for vineyard management in Sicily (Italy)

Wine quality depends on many factors, such as the choice of variety, stock, training system, pruning as well as environmental parameters and cultivation techniques performed in the vineyard. Monitoring the micro-climate of grapevine allows to conveniently perform the most important cultivation techniques (soil management, pesticide treatments, green pruning, harvest) thus reducing the operating costs of the vineyard, and increasing the overall quality of the grapes. The aim of the present study is to monitor the micro-climate of grapevine in order to control spring period hazards, to reduce the operating costs of the vineyard and to increase the quality of grapes. For this purpose a Wireless Sensor Network was used, and a comparison was performed between the data measured by wireless sensors and data provided by a fixed meteorological station of the local government agency (SIAS - Regione Siciliana). The results obtained here showed that, with reference to temperature, the data measured by wireless sensors are considerable different from the data of SIAS measuring station especially for temperatures above 20°C. With reference to relative humidity, there are no differences between the two types of sensors. Our study showed that the microclimate of the vineyard may be considerably different from the climate of the macro-area closest to the plot. Monitoring the micro-climate may thus be crucial as it may represent the key to a rational management of the vineyard, also with regard to a reduction of the costs of certain cultural operations.
