Resistive humidity sensors

Resistive humidity sensors measure the varition of a hygroscopic medium, such as a conductive polymer or a substrate, impregnated with a saline solution. The resistance change usually demonstrated an inverse dependence on humidity.

A typical design of such a sensor is represented by a substrate with the electrodes of noble metals, placed on it ...
