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 ...

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 ...

An AC bridge circuit can be used to measure the unknown capacitance of a sensor, such as a relative humidity (RH) sensor. Some RH sensors have a transfer function of capacitance vs %RH. Usually the ...

Editor’s note: The KOIN 6 Weather team is presenting weather and science lessons to help serve our teachers and students. Click here for more lessons. PORTLAND, Ore. (KOIN) – I would like to preface ...

An HVAC technician must measure water temperatures, as well as dry bulb and wet bulb temperatures of air. For example, you may have to measure the entering and leaving temperatures for a coil - both ...

Model SRH relative humidity sensor series product line is designed to measure relative humidity in a room, duct, or outside and is available in accuracies of ±2, ±3, and ±5 percent. The units ...

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

Dew point/relative humidity questions come up fairly often and this is a good one. Water vapor in the atmosphere is pretty important for deep-sky observing and photography. The atmosphere can only ...

It's been quite humid in the Brazos Valley over the last week, but how might you measure that humidity from home? We have a fun activity that you can do with everyday items. Now bear with me here, but ...

Exhaled breath humidity measurement is proportional to the amount of water vapor that is being lost by a human body. In this module, a Raspberry Pi with the SenseHAT is programmed to measure relative ...
