embedded temperature based fan speed controller using 89c51 microcontroller

Abstract

Temperature controller can be done by using Electronic circuit, Microprocessor or microcontroller. Now microcontroller is advanced among all above circuits therefore we are using Microcontroller for temperature controlling.In this project, microcontroller 89s51 forms the processing part, which firstly receives data from ADC. ADC receives data from temperature sensor through amplifier. Then microcontroller 89s51 performs the comparison of current temperature and set temperature as per the logic of program for which microcontroller has already been programmed. The result obtained from the above operation is given through output port of 89s51 to LCD display of relevant data and generated pulses as per the logic program which is further fed to the driver circuit to obtain the desired output of ceiling fan.

Introduction

Embedded Temperature Based Fan Speed Controller using 89C51 Micro controller project explains about developing a standalone application through which user can control speed of fan as per the requirement. Developing this application using micro controller will make a closed loop feedback system more efficient and reliable. In this project we use AT89C51 micro controller which makes the system user-friendly. It is very compact using few components and can be implemented for several applications including air-conditioners, electric heaters and many other electronic home applications.
