2. Introduction
 The Sensors are devices that responds to a physical stimulus
heat, light, sound, pressure, magnetism, motion, etc , and
convert that into an electrical signal.
 They perform an input function
 The Devices which perform an output function are generally
called Actuators and are used to control. some external device,
for example movement.
 Both sensors and actuators are collectively known as
Transducers. Transducers are devices used to convert energy
of one kind into energy of another kind.
