Film Humidity Sensors Using Thin Films for Moisture Detection

Film humidity sensors are critical devices that measure moisture levels in various applications to prevent water damage. They employ thin films capable of detecting and responding to changes in humidity.

How Do Film Humidity Sensors Work?

The thin films used in these sensors are composed of hygroscopic materials that absorb moisture from the air. As the moisture content changes, the film’s electrical properties, such as capacitance or resistance, are altered. These changes can be measured using electronic circuits, providing an accurate measure of the humidity level.
