For the monitoring of hydrometeorological variables, and more generally, for decision support systems, the instrumental in-situ measurement is crucial.

Referring to professional micrometeorological stations, there is a problem represented by the high costs of measures.

The high cost can be substantially related to the quality of the materials, to the array of industrial production processes and to the costs of skilled workers, needed for the installation and for the maintenance of the equipment.

A further problem in the development of such measuring networks is represented by "closed" products which, for structural layouts, data management and communications, are almost always referred to as "proprietary protocols", which push the customer to a perpetual and often non-negotiable "loyalty" to the supplier.

This limits the development of modern and efficient measurement networks in countries with limited economic resources.
