Arduino based Fan Speed Control System

The ascent of temperature on the planet can be caused because of a few elements like an unnatural weather change, ozone harming substance discharge and numerous other such factors. Climate change is one of the most discussed logical issues of the previous 20 years. The worldwide temperature of the earth has expanded on a normal of about 0.8 degree Celsius (1.4 degree Fahrenheit) since 1880. Since the control of this rising temperature is not in our hands, we have built a project that helps us control the speed of the fan in a room depending on the rise and fall of the room temperature. This paper discusses temperature based fan control fan speed control and monitoring the system using an Arduino system. The system uses an Arduino board to implement a control system. The study was conducted with the design and manufacture of automatic fan control system. Along with Arduino, we have use a temperature sensor LM35 to sense the temperature of the room. The fan control system discussed in this paper is economical, efficient and very reliable.
