When referring to the mugginess of the air, meteorologists will point to dew point rather than relative humidity. Relative humidity is indeed a measure of how much moisture is in the air relative 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 ...

HVAC upgrade projects, such as chiller changeouts, are best done in suitable weather conditions that include appropriate temperatures and dry air. Unfortunately, that’s not always possible in ...
