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.

4. Smart Sensor
A smart sensor is an analog/digital transducer combined with a
processing unit and a communication interface. It consists of
tranduction element, signal conditioning electronics and
controller/processor that support some intelligence in a single
package.
The integrated sensors wich has electronics and the transduction
element toghether on one silicon chip, this system can be called
as system on chip (SoC). The main make an intellegent sensor,
wich can be called as smart sensor. Smart sensor then have the
ability to make some decision.
