In some cases, relative humidity cannot be measured directly. This is particularly the case where the measurement conditions do not physically allow the use of an impedance variation sensor, for ...

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 measurement of relative humidity in a climatic environment - The main types of hygrometer for measuring or determining relative humidity and associated uncertainty ...

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 ...

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 ...

Abstract: Relative humidity (RH) and temperature sensing is a vitally important research field due to its various applications in the environmental, industrial, and agricultural monitoring. In this ...

Abstract: This paper proposes a solution for relative humidity measurement using data acquisition system NI PCI 6221 and LabVIEW. This solution combines virtual instrument with physical ...

Some sensors output a processed analog signal that is linear with respect to the physical quantity being measured. Some perform quantization as well and provide a digital output. Though it is easy to ...
