             abstract = "The growing interest for the environmental monitoring has led the 
                         improvement in the development of new materials for manufacturing 
                         of sensor fixtures more reliable, more versatile and at lower 
                         cost. In this sense, ceramics have a unique structure, consisting 
                         of grains, grain boundaries, surfaces and pores, the control of 
                         which permit the attainment of suitable microstructures to be used 
                         as sensor elements. In this way, the present work tries to bring 
                         together the technologies of manufacturing, characterization and 
                         development of porous ceramics and the monitoring of soil water 
                         content in typical Brazil soils. And so, in order to improve the 
                         sensing capacity of these ceramic devices, electrical measurements 
                         were performed in different climatic conditions of controlled 
                         relative humidity and room temperature. For that, ceramics sensors 
                         microstructures were characterized through scanning electron 
                         microscopy (SEM), X-ray diffractometry (XRD) and Hg porosimetry 
                         techniques. Results evidenced that the ceramic devices presented a 
                         very promising response to the water molecules contained in soil 
                         samples selected for tests, under established climatic conditions. 
                         This is a subject of great originality in world-wide terms, mainly 
                         concerning to the influence of the pores form and its size 
                         distribution on the capacity of chemical and physical interactions 
                         of water molecules with the surface of the sensor material.",
