Want to sense air temperature? There’s a sensor for that. Particulate content in the air? There’s a sensor for that, too. Someone sneaking up on you? Get yourself some passive infrared sensors ...

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 ...

In a new study, researchers produced nanomaterials that could be used in developing more accurate sensors for healthcare in ...

A cutting-edge humidity sensing system has been unveiled, capable of monitoring human behaviors in real-time through the ...
