Introduction

While going through the paper about various innovative technologies in the modern electronics world we came across the concept of fuzzy in the paper titled “ Implementation of fuzzy temperature control using microprocessor”. We found this concept to be quite interesting and we decided to implement this concept using microcontroller.
When Lotfi Zadeh introduced the world to fuzzy logic in 1965, he forgot to include, or rather was unprepared to include a user's manual., the Though he created fuzzy logic as a mathematical discipline that would allow designers create systems directly from human intuition and experience, the practice of actually applying it has for many years been a rather trial and error, arbitrary art. In other words, fuzzy logic's development methodology has remained a rather open issue. As a result initial users of fuzzy logic in real-world applications were intrepid researchers such as Abe Mamdani in the field of control engineering and Hans Zimmermann in business modeling. Today, this situation is much different. Fuzzy logic has become a commonly used technology and through the large number of successful applications development tools, as well as a development methodology, have evolved. The methodology has become part of an upcoming extension of an International Electrotechnical Commission standard (IEC 1131-3), providing designers with a guide through all steps of a fuzzy logic development project. With such standardized methodology, designers will be relieved from spending exuberant amounts of time experimenting with fuzzy logic before they can use it in their applications. Even better, designers will not need to study long and dry standards reports, because the upcoming generation of fuzzy logic design tools already incorporate much of this standardized methodology in their development environments.
The main aim of this project is to designed a system that can control the temperature of devices on the basis of fuzzy logic , and when the temperature exceeds the desired limit , the user is informed about the limit being exceeded using sms .In ihis report we are discussing the various components used and how to design a PCB.
