Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...

Have you ever found the need to measure the capacitance of a capacitor? No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no ...

A capacitor measured with a $100 handheld multi-meter can give a substantially different result than the same capacitor measured with a $10,000 LCR meter. That same capacitor measured with two ...

Ceramic capacitors are pretty much the pixie dust of the electronics world. If you sprinkle enough of them on a circuit, everything will work. These ceramic capacitors aren’t the newest and latest ...

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 ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

This paper defines a method to measure the chip die pad capacitance using time delay reflectometry (TDR). This method is useful for measuring the low-value capacitance that is present at the end of a ...

WHEN we consider that all matter is composed of electric ions which are in constant oscillation, it is evident that the study and measurement of electrical oscillations must always remain a leading ...

ABB has announced the development of a portable capacitance meter, the CB-2000, that is simpler to use and easier to carry than any other measuring devices previously available. ABB has announced the ...
