Abstract
This work deals with the sensitivity to moisture rate in air of perovskite with general formula YCr(1−x)MnxO3 with x ranging from 0 to 0.8. The combined sensitivity to moisture and temperature let us think the possibility of realizing composite sensors temperature/moisture. This study clearly shows the influence of the Mn content on moisture which affects the working frequency of sensors. Capacitance variation of the most sensitive compositions increases from 100 pF to 1 nF for relative humidity between 20 and 80%. The influence of porosity is also demonstrated.
