                         applied in several areas, since automotive and food industries up 
                         to automation in the agricultural production and in the 
                         environmental monitoring. In this work, ceramic material are 
                         focused, owing to their unique structure, consisting of grains, 
                         grain boundaries, surfaces and pores, the control of which allow 
                         to obtain suitable microstructure to be used as humidity sensors. 
                         In this work, the influence of the relative humidity on the 
                         electrical conductivity of the ceramic sensing elements of ZrO2 
                         and of TiO2, under specific climatic conditions, is investigated. 
                         In this sense, the ceramics used as humidity sensing elements were 
                         manufactured through conventional ceramic processing. The sintered 
                         ceramics were characterized through X-ray diffractometry 
                         techniques, scanning electron microscopy, apparent density by the 
                         Archimedes principle and linear retraction. The results showed the 
                         development of a solid solution of ZrO2-TiO2. The microstructures 
                         presented a homogeneous distribution of pores. The ceramic 
                         tablets, sintered at 1100 C, evidenced a linear behaviour in the
