A generic term that is used to describe many types of temperature sensors.
Any device that receives a signal or stimulus (as heat or pressure or light or motion etc.) and responds to it in a distinctive manner
The part of the transducer which reacts directly in response to the measurand.
A device that detects or measures something by converting nonelectrical energy to electrical energy. A photocell, for example, detects or measures light by converting it to electrical energy. See also transducer.
(Homonym: censer, censor).
That which senses; a device used to sense such states as temperature, pressure, etc.
In computing, a device designed to detect a physical state or measure a physical quantity, and produce an input signal for a computer.
For example, a sensor may detect the fact that a printer has run out of paper or may measure the temperature in a kiln.
The signal from a sensor is usually in the form of an analog voltage, and must therefore be converted to a digital signal, by means of an analog-to-digital converter, before it can be input.
