Of all common environmental parameters, humidity is perhaps the least understood and most difficult to measure. The most common electronic humidity detection methods, albeit highly accurate, are not ...

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 ...

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 ...

Relative humidity is a simple concept as weather phenomena go – but it has significant, far-reaching consequences for how we must take care of ourselves on a hot or wet day. Humidity is the amount of ...

Wondering what humidity is comfortable? While we often give a great deal of thought to heating our homes in the winter and cooling them down in the summer, we may not realize just how crucial ...
