Focus on moisture and humidity
Moisture generally refers to the presence of water, often in small amounts. Humidity
is the amount of water vapor present in the air. Humidity is commonly taken to mean

relative humidity. Relative humidity is defined as the ratio of the partial pressure of water   sensor
vapor in a parcel of air to the saturated vapor pressure of water vapor at a prescribed tem-
perature. Humidity can be expressed as absolute humidity and specific humidity as well.
