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 ...

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 ...

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" ...

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 ...

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 ...

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 ...

Welcome to Pharmaceutical Technologies Podcast Series, "Do you really know your Relative humidity calibration vendor?" Our sponsor, Rotronic, is a technology leader in the field of relative humidity ...

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 ...
