Automatic temp control fan

Photo Credits:. The automatic fans will change its speed according to the temperature in the room. When the button is pressed, the speed can controlled by manually that means user can control the fan speed manually.

Temperature Controlled DC Fan using Microcontroller The proposed system temperature controlled fan using microcontroller is used to control the speed of the fan according to the temperature and specify the temperature in the display.

We hope that you have got a better understanding of this concept.

The main function of the microcontroller in the proposed system is to analyze the temperature which is sensed by the temperature sensor. The main intension is to control the fan by heating the sensor, i.

Here is a question for you, what is the function of 7-segment display? If light emitting diode is blinking, it means the fan control is manual.
