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 ...

Abstract: This work presents a microwave system for measuring relative humidity in 14 cm-thick hollow concrete blocks, aiming to establish a technique for structural integrity monitoring. Five block ...

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

Features of the new TI relative-humidity sensor family. The RH sensor's dual capability of measuring temperature. Applications for the HDC302x family. Temperature is the most widely measured ...

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 ...
