Polymer humidity sensor SJ The series is a new generation of composite resistance-type humidity-sensitive components. The complex impedance is exponentially related to the relative humidity of the air. The DC impedance (measured by ordinary digital multimeter) is almost infinite. It has the ionic conduction of water molecules in the air in the membrane moisture sensing. Since water molecules are polar molecules, they will ionize and decompose in the presence of DC, which affects the conductivity and the life of the component. Therefore, it is required to use an AC circuit to sense....
