Transducers.

A transducer is a device, usually electrical, electronic, electro-mechanical, electromagnetic, photonic, or photovoltaic, that converts one type of energy or physical attribute to another for various purposes including measurement or information transfer (for example: pressure sensors).

There are three kinds of transducers. A sensor is used to detect a parameter in one form and report it in another form of energy (usually an electrical or digital signal), such as a tachometer. An actuator is used for the transformation of energy or in other words, actuator is the one which gets actuated or stands responsible for the output action, in that it converts electrical signal into generally nonelectrical energy. An example of an actuator is a loudspeaker which converts an electrical signal into a variable magnetic field and, subsequently, into acoustic waves. The third kind of transducer has both functions -- acting as an actuator to produce ultrasonic waves, and acting as a sensor to detect ultrasonic waves.

Sensors.

A sensor is a device that measures a physical quantity and converts it into a signal which can be read by an observer or by an instrument. For example, a mercury thermometer converts the measured temperature into expansion and contraction of a liquid which can be read on a calibrated glass tube. A thermocouple converts temperature to an output voltage which can be read by a voltmeter.

Sensors are used in everyday objects such as touch-sensitive elevator buttons and lamps which dim or brighten by touching the base. There are also innumerable applications for sensors of which most people are never aware.

  A sensor's sensitivity indicates how much the sensor's output changes when the measured quantity changes. For instance, if the mercury in a thermometer moves 1 cm when the temperature changes by 1°C, the sensitivity is 1 cm/°C. Sensors that measure very small changes must have very high sensitivities. Sensors also have an impact on what they measure.  Sensors need to be designed to have a small effect on what is measured, making the sensor smaller often improves this and may introduce other advantages.
