ABSTRACT
This project is used to control the fan speed according to the temperature and it
also indicates the temperature. The system will get the temperature sense from the
temperature measuring IC corresponding to which temperature digits are obtained
and displayed and it will control the speed of fan according the duty cycle(PWM)
values stored in a lookup table according to the temperature measured .

ACKNOWLEDGEMENT
We wish to express my deep sense of gratitude and indebtedness to our guide, Mr. Ravi Prakash
Sharma Department of Electrical Engineering, for their invaluable guidance, advice and
encouragement throughout this work. Their moral support, affectionate relationship and
unreserved cooperation, which enabled us to complete this thesis successfully, will be last
forever in my memory.
We wish to thank for their whole-hearted cooperation and encouragement provided for this
endeavor.A special thanks to the entire faculty, staff and our friends of Electrical Engineering
Department, for their cooperation. Words are inefficient to express our gratitude to our family
members for their inspirations, blessings and support. We thank God, who has supported us at
every moment.
