             abstract = "Presently, there is a lack of effectiveness in the manufacturing 
                         of sensors and sensing systems, with Brazilian technologies and 
                         raw-materials, able to measure soil water content, with efficiency 
                         and practicality. On account of this, ceramics is selected as 
                         sensing elements for this application, based on relevant results 
                         obtained by researchers from the TECAMB Group of INPE, along the 
                         last 15 years. 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, for several applications, such as 
                         irrigation, drainage, building and environmental monitoring as 
                         well. 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. The scanning electron microscopy technique was 
                         applied for the morphological analysis of the sintered ceramic 
                         microstructure. 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.",
