A CMOS MEMS Humidity Sensor Enhanced By A Capacitive. humidity sensors [6,7], optical humidity sensors [8,9], capacitive humidity sensors [10,11] and so on. Among them, capacitive humidity sensors are widely used because of advantages of low power consumption, good performances and long-term stability [4,12].
Humidity Sensors Principle, Mechanism, And Fabrication. Then, a classification of humidity sensors and the related applications are given in Section 3. The principle of ceramic humidity sensor operation based upon hydrogen permeation and water protonation is detailed in Section 4. Whilst Section 5 provides a survey of impedance type sensors, Section 6 covers capacitive type transducers. A
Resistive Humidity Sensor. HR202 is a new kind of humidity-sensitive resistor made from organic macromolecule materials, it can be used in occasions like: hospitals, storage, workshop, textile industry, tobaccos, pharmaceutical field, meteorology, etc.
Humidity Sensors: Capacitive Vs. Resistive. Capacitive Sensors. Humidity and dew sensors, also called hygrometers, are necessary when consistent environmental conditions are required to be maintained. A capacitive humidity sensor is so named because it uses capacitive measurement, which relies on electrical capacitance. These are a common type of humidity sensors.

Most capacitive sensors use a plastic or polymer as the dielectric material, with a typical dielectric constant ranging from 2 to 15. In absence of moisture, the dielectric constant of the
