Biological research in agriculture needs a lot of specialised electronic sensors in order to fulfil different goals, like as: climate monitoring, soil and fruit assessment, control of insects and diseases, crop tracking, and so on. That research must be supported by consistent biological models able to simulate diverse environmental conditions, in order to predict the right human actions before risky biological damage could be irreversible. In this paper, an experimental distributed network based on climatic an biological wireless sensors is described. This system provides real measurements in order to validate different biological models used for viticulture applications.
