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}. (1997-04-15)
