		<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.</abstract>
