Capacitive humidity sensors | Choosing the right humidity sensor
There are three main types of sensors: Capacitive humidity sensors They consist of a layer of moisture-sensitive dielectric material placed between two electrodes, thus forming a capacitor whose capacitance varies linearly with relative humidity. They measure relative humidity from 0% to 100%. They also provide high-precision atmospheric measurements. This type of sensor is used in industry and meteorology. Resistive humidity sensors Measure the...
