Click on the link above for more information on this project.
In this project, microcontroller 89s51 forms the processing part, which firstly receives data from ADC. ADC receives data from temperature sensor. 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.
