In the conclusion, we gave some statements about the limitations and the scope of future enhancement of the project. The results show how effective this work is in practical life. Hardware requirements, Software requirements, block diagrams descriptions of the component used in the project, and the flow chart were discussed. In order to achieve effective cooling, two fans are used and run one by one according to the thermal load in the place rather than using one big fan in order to lessen the consumed electrical load. Arduino microcontroller is used to control the input/output of the system using PWM (Pulse width modulation). In this project, a Microcontroller Arduino type forms the processing part after sensing the temperature using an N-type thermistor (Temperature sensor). So in this project, we will provide to control the turning on/off of the fan with respect to the temperature set rather than the use of a manual switching system. We are moving toward automation day after day by the use of "INTERNET OF THINGS (IoT)", which connects the different sensors, actuators, and other embedded devices. Finally, the designed system circuit is tested in many times and performed very well.Īs we know that automatic system and automation is the requirement of today"s technology. As an additional feature LCD is used to present the temperature and the fan speed. A circuit with LM35DZ temperature sensor, PIC16F877A microcontroller, brush less DC motor and few of electronic components is designed and implemented to control the fan speed automatically.
In this paper, an automatic control solution is suggested to control the fan speed. Usually, when the temperature is high the fan set at high speed and at lower temperatures the fan is operated with lower speed. The fans are generally available with speed control, depending on the requirement the speed is set.
the distinct characteristic of automatic control is that it reduces the human operator. Automatic control is vast technological area whose central aim is to develop control strategies that improve performance when they applied to a system. Automatic controls play an ever-increasing role in a human way of life.
