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 ...

When referring to the mugginess of the air, meteorologists will point to dew point rather than relative humidity. Relative humidity is indeed a measure of how much moisture is in the air relative to ...

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, ...

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 ...

My high school had a weather station on the roof so earth-science students could make measurements each morning. We climbed up a ladder in the janitor's closet, went through a hatch and out onto the ...

Relative humidity has been used to describe moisture levels in the atmosphere for so long that it has become the most common (though often misunderstood) moisture measurement. And there is truth to ...

YOUNGSTOWN, Ohio (WKBN) – There might not be a more misunderstood phrase in meteorology than “relative humidity.” Every summer when humidity returns, this phrase echoes across the United States: “It ...

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 ...

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 ...
