Abstract: The present invention relates to a humidity sensor, and more particularly, to a resistance film-type real-time chromogenic humidity sensor produced with a polyelectrolyte thin film. The humidity sensor according to the present invention is a chromogenic hygrometer in which a polyelectrolyte nano thin film that absorbs moisture is formed on a reflective layer, and the nano thin film varies terms of color and electrical resistance as moisture is absorbed and the thickness varies. The hygrometer according to the present invention is a dual-function hygrometer, the color and resistance of which vary. Provided is the chromogenic hygrometer in which the sensor made using a PSS-b-PMB thin film varies in color between purple, blue, green, yellow, orange, and red according to humidity at a very high response speed of within one minute.
