From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  sensor
       
           An electronic device used to measure a physical
          quantity such as temperature, pressure or loudness and convert
          it into an electronic signal of some kind (e.g a voltage).
          Sensors are normally components of some larger electronic
          system such as a computer control and/or measurement system.
       
          Analog sensors most often produce a voltage proportional to
          the measured quantity.  The signal must be converted to
          digital form with a {ADC} before the CPU can process it.
       
          Digital sensors most often use serial communication such as
          {EIA-232} to return information directly to the controller or
          computer through a {serial port}.
