Temperature Based Fan Speed Controller Using Arduino

The temperature based fan speed control system can be done by using an electronic circuit using an arduino board.

Temperature based fan speed controller using arduino.

In this arduino based project we are going to control dc fan speed according to the room temperature and show these parameter changes on a 16x2 lcd display. It is accomplished by the data communications between arduino lcd dht11 sensor module and dc fan that is controlled by using pwm. It is built around arduino uno board board1 16 2 lcd lcd1 temperature sensor lm35 ic1 and a few other components. Lm35 is a precision integrated circuit whose output voltage is linearly proportional to celsius centigrade temperature.

Circuit diagram of the temperature fan speed control and monitoring is shown in fig. Pwm is a technique by using which we can control voltage. Circuit diagram of the temperature based fan speed control and monitoring using arduino. The fanlcd re maps the temp to allow the display of fanspeed in a 0 to 100 range so you can say that the speed of the fan is directly dependent of the lm35 s temperature.

Now arduino board is very progressive among all electronic circuits thus we employed arduino board for fan speed control the proposed system is designed to detect the temperature of the room and. Arduino is at the heart of the circuit as it controls all functions.
