3 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Sensor \Sen"sor\, a. Sensory; as the sensor nerves. From WordNet r 1.6 [wn]: sensor n : anything that receives a stimulus (as heat pressure light motion etc.) and responds to it [syn: {detector}] From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: sensorAn 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}.
