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 ...

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 ...

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 ...

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, ...

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 ...

The S-503 relative humidity generator enables the user to calibrate relative humidity (rh) sensors and transmitters. It can generate and hold rh values from 10 percent to 90 percent in 0.1 percent rh ...

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 ...

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 ...

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 ...

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 ...

(WHTM) — When temperatures rise, sometimes the air can feel dry and comfortable. But, sometimes it can feel downright tropical outside. This is caused by moisture in the air and it makes the air ...
