With either option, you should monitor the temperatures of your CPU and other components and make sure youвЂ™re not causing damage to your system. Keep in mind that this will make your system run a lot hotter, and could lead to system instability if you let it go too far. On the other hand, if you hate fan noise, you can manually turn them down. This makes a lot of noise, which is why the auto-control tries to slow it down. Usually, this kicks in before the temperature gets too high, but you can manually push your CPU farther by turning the fan speed up farther than Apple usually allows.

Then the transistor creates a voltage according to the PWM input.Your Mac throttles your CPU when it gets too hot, slowing it down significantly until the temperature gets under control. We have created PWM at PWM pin of Arduino and applied it at base terminal of transistor. Here we have only used this DHT sensor for sensing temperature, and then programmed our Arduino according to the requirements. Here in this project we have used a sensor module namely DHT11 that are already have discuss our previous project namely вЂњHumidity and Temperature Measurement using ArduinoвЂќ. And last part of system shows humidity and temperature on LCD and Fan driver. Second section reads the DHT11 sensor moduleвЂ™s output and extracts temperature value into a suitable number in Celsiu s scale and control the fan speed by using PWM. One senses the temperature by using humidity and temperature sensor namely DHT11. PWM is a technique by using which we can control voltage. It is accomplished by the data communications between Arduino, LCD, DHT11 sensor Module and DC fan that is controlled by using PWM. 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.

Good for nighttime, when cooling loads are low and humidity is high.

Energy efficient, partly because it removes less moisture.

Good for daytime, when cooling loads are low and humidity high.

More cooling and less moisture removable.

The advantages of automatic fan control for air conditioning system mainly include the following.

The result obtained from the above operation is given through output port of a microcontroller to the 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 to fan. Then the microcontroller performs the comparison of current temperature and set temperature as per the logic of the program for which microcontroller has already been programmed. The temperature sensor is used to detect the temperature of that environment and send that information to the ADC then that result sends to the microcontroller. This system designed with microcontroller, FAN, temperature senso r and a DC motor. Now microcontroller is advanced among all above circuits therefore we are using microcontrollers for air conditioning such as the Arduino,

The automatic air conditioning system can be done by using Electronic circuit using Microprocessor or microcontrollers. So, an automatic temperature control system technology is needed for the controlling purpose in the fan speed according to the temperature changes.ДЄutomatic Fan Control for Air Conditioning System Except the usage change the speed of the fan which is manually. Where in this method, any change in the temperature will not give any change in the fan speed. Fan can be controlled manually by pressing on the switch button. One of the most important concerns involved in heat area consist in the desired temperature achievement and consumption optimization. Nowadays, the demand for accurate temperature control and air freshening control has conquered many of industrial domains such as process heat, automotive, industrial places or office buildings where the air is cooled in order to maintain a comfortable environment for its occupants. In fact, the fan has been long used and still available in the market. It is also one of the most sensible solutions to offer a comfortable and energy efficient. It is a common circuit and widely used in many applications. Electric Fan is one of the most popular electrical devices due to its cost effectiveness and low power consumption advantages.
