What is a sensor?
Sensor
Input Signal Output Signal
 American National Standards Institute (ANSI) Definition
 A device which provides a usable output in response to a specified
measure
 A sensor acquires a physical parameter and converts it into a signal
suitable for processing (e.g. optical, electrical, mechanical)
 A transducer – (A device that converts one form of energy into other)
 Microphone, Loud Speaker, Biological Senses (e.g. touch,
sight,…etc.)
A sensor is an object whose purpose is to detect events or changes in its
environment, and then provide a corresponding output
− 4 − Sensors
Sensors may provide various types of output, but typically
use electrical or optical signals
 A thermocouple generates a known voltage (the output) in response
to its temperature (the environment)
 A mercury-in-glass thermometer, similarly, converts measured
temperature into expansion and contraction of a liquid, which can be
read on a calibrated glass tube
