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 ...

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 ...

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, ...

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 ...

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 ...

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 ...

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 ...

Engineers now have two multifunctional transmitters at their fingertips for measuring relative humidity and temperature. The HT737 is a digital unit that measures ...

GRAND RAPIDS, Mich. (WOOD) — Humidity has a big impact on a forecast, and the dew point is a great way to measure how it will feel outside. Unlike relative humidity, which changes with the temperature ...
