Humidity
Humidity sensors are devices that are used to measure the humidity, or amount of moisture, in the air. Facilitating compliance with ASHRAE 62.1 standard for air quality, these sensors work by measuring the temperature and humidity of the air and using this information to calculate the dew point, or the temperature at which water vapor condenses from the air.
