# Temperature-Controlled-DC-Fan

# Abstract :

      ~ Generally, electronic devices produce more heat.

      So this heat should be reduced in order to protect the device.

      

      ~ The aim of this project is to design a Temperature Controlled DC Fan

      which automatically turns on a DC Fan when the temperature increases above

      a certain limit and also the temperature limit can be changed anytime using input from UART.

      

If the temperature exceeds 35 degree Celsius -> The microcontroller will turn on the relay.

(ambient temperature limit of laptop)            Now, 12V DC source is connected which starts the fan.

If the temperature drops below 35 degree Celsius -> The microcontroller will turn off the relay ,

                                                    but the fan speed will slow down gradually

                                                    which further reduces the temperature.
