Relative humidity is reported as a percentage of the total amount of moisture that could be held in the air. For instance, if the air is only half saturated with water vapor, the relative humidity will be reported at 50%. If the air holds all the water vapor it can hold, it is 100% saturated. Relative Humidity Technology. A capacitance-type sensor is one way to measure relative humidity. Changes in relative humidity cause the shape of the sensor to change.
