Air movement is measured using anemometers. Air speeds inside a building tend to be relatively low, usually less than 1 m/s. This means the anemometers used for this purpose have to be much more sensitive than those used in weather stations measuring wind. There are two main types of internal anemometer, those based on a small propeller and those based on the cooling of a hot metal wire exposed to the air. Propeller based systems tend to be a little less sensitive at very low air speeds, however bearing technology and ultra-lightweight materials are increasingly proving this to be incorrect. Below is a picture of a anemometer.

Air temperature can be measured beyond the troposphere.

The thickness or thinness of the air is typically measured in terms of air pressure, which is commonly measured in units of millibars or inches of mercury. These measurements indicate the weight of the air above a specific point, with higher pressure readings indicating denser air (thicker) and lower pressure readings indicating less dense air (thinner).
No, humidity is measured as a percentage. It represents the amount of water vapor present in the air relative to the maximum amount the air can hold at a given temperature.

Pressure is the physical quantity measured in bar.
Air temperature is typically measured using a thermometer, which is a device that detects and displays the temperature of the surrounding air.
It is measured in inches of Mercury, millibars, and hectoPascals.
Air pressure is measured in bar.
Air pressure is the force exerted on an object or area by the weight of the surrounding air particles.Air pressure is measured by Barometer.
The property measured in grains is the amount of moisture in the air, known as humidity. Grains per pound (GPP) is a common unit of measurement for humidity in the air.
