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 ...

GREENSBORO, N.C. — Two common weather terms you'll hear many times in the warmer part of the year are "dew point" and "relative humidity". While both relate to moisture in the air and the "stickiness" ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

(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 ...
