3. INTRODUCTION
 An Embedded System is one that has
computer-hardware with software
embedded in it as one of its most
important component. It is dedicated
computer-based system for an
application's or product. It may be either
an independent system or a part of larger
system. An Embedded System is a
special-purpose computer system
designed to perform one or a few
dedicated functions.

9. APPLICATIONS OF EMBEDDED
SYSTEMS
 Audio like mp3 players
 Cellular telephones and telephone switches
 Engine controllers and antilock brake controllers
for automobiles
 Home automation products, such as thermostats,
air conditioners, sprinklers
 Handheld calculators
 DVD players and recorders
 Medical equipment
 Computer peripherals such as routers and
printers

10. TEMPERATURE PROGRAMMER
 In many area’s of daily and technical life, making
temperature measurements is the most
important instrumentation task.”Intelegent”digital
sensors, which can do more than just output
temperature readings, are winning more ground
as compliments to classical analogue techniques.
An example of such a sensor is the Dallas
Semiconductor DS1621.
 Naturally, the main job of a modern digital
temperature sensor is to determine the current
temperature. It does this by measuring its own
temperature, which is nearly the same as the
temperature of its surroundings, and converting
this analogue temperature value into a digital
word that it sends to a microcontroller via a serial
interface.

13. ADVANTAGES
 Debugging: Embedded Debugging may be
performed at different levels from simplest to
most sophisticated depending on the facilities
available.
 Reliability: Embedded systems often reside in
machines that are expected to run continuously
for years without errors and in some cases
recover by themselves if an error occurs. Thus
are reliable.
 Portability: Embedded System have greatly
reduced the size of its’ various application. Thus it
has become easy to handle.
 Economic: Recent technologies have reduced the
prices to a great extent.

14. CONCLUSION
 Today in this fast moving world, everyone wants
to handle small and portable products which are
comfortable to them. Thus embedded systems
are proving blessings for them. The growing
needs of various applications such as home
appliances, various hard wares, industrial needs
etc have demanded development in this field.
Satellite developments are also demanding the
growth of embedded system. It has become part
of our life in form of mobile phones, laptops and
various other appliances. Temperature
Programmer is project that employ embedded
system. There are lots many projects based on
embedded system and have some or other
application and can be used in various products
