n.
1. A device, such as a photoelectric cell, that receives and responds to a signal or stimulus.

sensor

(ˈsɛnsə)
n
(Electronics) anything, such as a photoelectric cell, that receives a signal or stimulus and responds to it
[C19: from Latin sēnsus perceived, from sentīre to observe]

sen•sor

(ˈsɛn sɔr, -sər)

n.
1. a mechanical device sensitive to light, temperature, radiation level, or the like, that transmits a signal to a measuring or control instrument.
[1925–30]

sen·sor

(sĕn′sər)
A device that responds to a physical stimulus and converts the stimulus into a signal conveyed to another device. For example, a sensor in a printer detects that the paper tray is empty and sends a signal to the digital display that the tray is out of paper.

sensor

An equipment which detects, and may indicate, and/or record objects and activities by means of energy or particles emitted, reflected, or modified by objects.

sensor

A device for sensing and measuring light, pressure, or temperature, and sending information back to a computer.
