                         minimize the potential risk of landslide in hillsides and to 
                         prevent new disasters, has led the improvement in the development 
                         of new materials for manufacturing of capacitive sensor devices 
                         more reliable, more versatile and at lower cost. In this sense, 
                         ceramics have shown advantages from the point of view of 
                         mechanical resistance, resistance to chemical attacks and physical 
                         and chemical stability in aggressive environments. In addition, 
                         these materials 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 moisture 
                         sensors. The goal of this work is to investigate the capability of 
                         porous ceramics sensor devices, developed in National Institute 
                         for Space Research (INPE), to monitor the soil water dynamics. For 
                         that, ceramics sensors microstructures were characterized through 
                         scanning electron microscopy, X-ray diffraction and Hg porosimetry 
                         techniques. Electrical measurements were performed in function of 
                         water portion addition in soil samples, up to the saturation 
                         limit, as it happens in area with landslide risk in periods of 
                         rain. The analyses of the results evidenced that the ceramics 
                         devices are promising ones concerning to their potential in the 
                         monitoring of environmental parameters.  (2014) Trans Tech
