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 ...

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 ...

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 ...
