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.",
