The development of a wireless sensor network for soil moisture measurements, in a wide reference area of 10 脳 10 km2, is described in this work. Some automatic measurement stations were strategically placed following soil homogeneity and land uses criteria. These stations include acquisition, conditioning and communication sys- tems. The electronics are operated by a solar panel fed bat- tery, in order to allow them to operate autonomously. The collected data are then transmitted by radio links, with link ranges up to 8 km. A standard PC is used to control the whole network and store the data. This computer also al- lows accessing the data via Internet for its subsequent anal- ysis. Even though the specific application was the charac- terization of a reference area, in order to use it in campaigns of calibration and validation of the space mission SMOS (Soil Moisture and Ocean Salinity), the system is easily ex- tensible to other climatic measurements as well as for other zones of interest.
