In general, "sensor" refers to any technical component that independently detects certain physical or chemical variables and properties in the environment or of objects. This can be, for example, the temperature, brightness or acceleration. In this sense, sensors are similar to our sense organs - only that, unlike the latter, they also register things that would otherwise remain invisible to humans or would be too dangerous.
Thanks to semiconductors, accelerometers, motion sensors and capacitive touchscreens can be found in even the smallest devices, making it easier than ever to use smartphones and tablets. But especially in industry, sensors and proximity switches are absolutely indispensable. They not only ensure the safety of machines but also of the people who operate them. Click here to read more
