Translation of "sensor" into Czech

Any hardware or software that can detect events or environmental changes, such as your current location or the amount of light around your computer. For example, a notebook with a location sensor, such as a Global Positioning System (GPS) receiver, can determine your exact location. An ambient light sensor can detect when there is a change in lighting, and then a program can use that information to adjust the brightness of your screen. [..]

The generic name for a device that senses either the absolute value or a change in a physical quantity such as temperature, pressure, flow rate, or pH, or the intensity of light, sound, or ratio waves and converts that change into a useful input signal for an information-gathering system.
