If it’s DC, the easiest way is to use a shunt resistor and measure the voltage across it, and for AC you could use a current transformer. But the advent of the Hall-effect sensor has provided us ...

Current sensors measure AC and/or DC current levels. The sensors in this selection guide measure current and provide some sort of output that corresponds to the current being measured. The most ...

Eddy current proximity sensors and switches detect the proximity or presence of a target by sensing fluctuations in a magnetic field generated by a reference coil. The variations in this field are due ...

Have you been paying attention to current events recently? See how many of these 10 questions you can get right. A year into this devastating war, what are you feeling and thinking? How have your ...

Current. Too little of it, and you can’t get where you’re going, too much and your hardware’s on fire. In many projects, it’s desirable to know just how much current is being drawn, and ...

The role of chancellor at the University of Oxford has been around for 800 years. This year, a particularly broad range of people have applied. By Mark Landler Before Hamas’s Oct. 7 attacks ...

You can save a lot of money and hassle by installing a smart water sensor. The best models we've tested immediately alert you to leaks and even shut off the water ...

Jacob Wackerhausen / Getty Images While the current yield and yield-to-maturity (YTM) formulas may be used to calculate the yield of a bond, each method has a different application—depending on ...

"I will put Detroit first. I will put Michigan first." 'The world is on fire, and I’m not that interested in laundry-folding content,' the 'Succession' actor says of his new role in 'The ...

Both sensors measure rate of change; they just measure the rate of change for different things. In practice, that means that an accelerometer will measure the directional movement of a device but ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level ...
