There are three ways to measure relative humidity. Current automated weather systems measure the reflection of a beam of light on a mirror. The mirror is chilled until atmospheric moisture condenses ...

Dew point can be calculated using the air temperature and a relative humidity value, which is measured using something called a sling psychrometer. A psychrometer is a metal rod, around 6 inches long, ...

CORPUS CHRISTI, Texas — You see it all the time. The humidity is 100%! So humid! Air you can wear! While that may be true *at times*, it doesn't paint the full picture. When humidity is expressed as a ...

Air pollution is not taken into consideration. Actually, relative humidity is not directly measured. The air temperature and dew point temperature are measured, and the relative humidity is then ...

A relative humidity meter can be built using a sensor with a capacitive response and a PIC microcontroller (MCU), as shown in the figure. The capacitance range of the sensor, the HS1101 from Humirel ...

PHILADELPHIA (CBS) -- You may have noticed that in our broadcasts here on CBS3, we constantly refer to a thing called the "dewpoint" during the summer months. Many have asked "what about the relative ...

BRYAN, Texas (KBTX) - When you watch the KBTX Pinpoint Weather Team forecast a day of weather in the Brazos Valley, you may hear phrases like “95 degrees with 80 percent humidity” used. But what does ...

“Relative humidity”, in a gross over-simplification, is the amount of moisture present in the air compared to how much moisture COULD be present at a given temperature. True meteorologists will ...

If you get your current weather information in the morning, you should know that the morning relative humidity is not a useful indicator of how humid the weather will be today. In fact, the relative ...

Water vapour is fundamental to life on Earth. As well as being a greenhouse gas, water vapour is the basis for clouds and rain. Therefore, it sustains plants, forests and our ability to grow food. A ...
