Temperature Based Fan Speed Controller Using Arduino Code

This code demonstrates how to construct digital temperature controller using arduino.

Temperature based fan speed controller using arduino code.

The output from sensor is directly. Pwm is a technique by using which we can control voltage. It utilizes arduino board as controlling device and atmega328 as a micro controller. Circuit diagram of the temperature based fan speed control and monitoring using arduino circuit diagram of the temperature fan speed control and monitoring is shown in fig.

The given project is a demonstration of such system. If it is less it will turn off the relay. These values are used to control the speed of the fan using pwm and the analogwrite. The temperature based fan speed control system can be done by using an electronic circuit using an arduino board.

So all these are basic building blocks of temperature controller system. Speed of fan can be varied by changing the input supply if w need to change the fan speed depends on temperature changes means we can implement the following application note with arduino and temperature sensor lm 35. In this post we have described how to design temperature based fan speed control monitoring with arduino and lm35 temperature sensor. It is accomplished by the data communications between arduino lcd dht11 sensor module and dc fan that is controlled by using pwm.

Circuit diagram construction and working this circuit constructed with arduino uno board as a main part and lm35 as a temperature sensor. 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. Temperature based fan speed control. 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. We have used combination of lcd and temperature sensor lm35 to make simple temperature controller using arduino. It is built around arduino uno board board1 16 2 lcd lcd1 temperature sensor lm35 ic1 and a few other components.
