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 the future. For example, the levels of female hormones are so low that very ...

Researchers at the University of Turku, Finland, have succeeded in producing sensors from single-wall carbon nanotubes that ...

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