Humidity

Humidity is a term for the amount of water vapor in air, and can refer to any one of several measurements of humidity.
Formally, humid air is not "moist air" but a mixture of air and water vapor, and humidity is defined in terms of the water content of this mixture, called the Absolute humidity. In everyday usage, it commonly refers to relative humidity, expressed as a percent in weather forecasts and on household humidistats; it is so called because it measures the current absolute humidity relative to the maximum. Specific humidity is a ratio of the water vapor content of the mixture to the dry air content.
The water vapor content of the mixture can be measured either as mass per volume or as a partial pressure, depending on the usage.

In meteorology, humidity indicates the likelihood of precipitation, dew, or fog. High relative humidity reduces the effectiveness of sweating in cooling the body by reducing the rate of evaporation of moisture from the skin. This effect is calculated in a heat index table, used during summer weather.

Here at Thermal Systems we can provide you with many different types of humidity sensors to suit you applications, whether it be on an industrial scale or consumer scale.

Icespy System5 supports the use of a humidity sensor, which acts just like a normal Scout+ but reads the data as relative humidity in a percentage.
