Relative humidity, or RH, is the percentage of moisture in the air referenced to the maximum level of moisture the air can hold at that temperature and pressure. Early humidity sensors used natural ...

(Nanowerk Spotlight) Each exhaled breath carries distinct signatures of human activity - quick and shallow during exercise, deep and regular in sleep, irregular while speaking. These breathing ...

Here’s a guide to evaluating and using the latest generation of 3D magnetic sensors, which offer a higher-accuracy alternative to existing 1D Hall-effect sensors. Linear magnetic sensing is becoming ...

The sensors can withstand the high vibration and severe shock environment found in steel, aluminum, and paper mills, as well as extremes of temperature and humidity found in most outdoor applications ...

Most LDVT components are protected against the environment to some degree. But there are applications where more protection is needed. LVDTs, or linear variable differential transformers, are ...

Melexis has brought out a linear Hall-effect sensor that draws less than 5 µA at 100 Hz and integrates digital filters for enhanced performance. Its flexible architecture is available in multiple ...
