INTRODUCTIONINTRODUCTION An An Embedded SystemEmbedded System is one that has is one that has

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

In many area’s of daily and technical life, making In many area’s of daily and technical life, making temperature measurements is the most temperature measurements is the most important instrumentation task.”Intelegent”digital important instrumentation task.”Intelegent”digital sensors, which can do more than just output sensors, which can do more than just output temperature readings, are winning more ground temperature readings, are winning more ground as compliments to classical analogue techniques. as compliments to classical analogue techniques. An example of such a sensor is the Dallas An example of such a sensor is the Dallas Semiconductor DS1621.Semiconductor DS1621.

Naturally, the main job of a modern digital Naturally, the main job of a modern digital temperature sensor is to determine the current temperature sensor is to determine the current temperature. It does this by measuring its own temperature. It does this by measuring its own temperature, which is nearly the same as the temperature, which is nearly the same as the temperature of its surroundings, and converting temperature of its surroundings, and converting this analogue temperature value into a digital this analogue temperature value into a digital word that it sends to a microcontroller via a serial word that it sends to a microcontroller via a serial interface. interface.

performed at different levels from simplest to performed at different levels from simplest to most sophisticated depending on the facilities most sophisticated depending on the facilities available.available.

ReliabilityReliability: Embedded systems often reside in : Embedded systems often reside in machines that are expected to run continuously machines that are expected to run continuously for years without errors and in some cases for years without errors and in some cases recover by themselves if an error occurs. Thus recover by themselves if an error occurs. Thus are reliable.are reliable.

PortabilityPortability: Embedded System have greatly : Embedded System have greatly reduced the size of its’ various application. Thus it reduced the size of its’ various application. Thus it has become easy to handle.has become easy to handle.

EconomicEconomic: : Recent technologies have reduced the Recent technologies have reduced the prices to a great extent.prices to a great extent.

CONCLUSIONCONCLUSION Today in this fast moving world, everyone wants Today in this fast moving world, everyone wants

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