Automatic control is a vast technology area with a central focus on developing control strategies that increase productivity when applied to a system. A distinctive feature of automatic control is that it reduces the number of people-operators. One such gadget is a fan. Fans are usually available with variable speed
This microcontroller has inbuilt PWM module which is used for controlling the speed of the fan by changing the duty cycle. Fan Speed Control System using PIC16F877A Microcontroller. According to the temperature sensor readings, the duty cycle will be automatically changed for controlling fan speed. The microcontroller will send the PWM signal

The 2N2222 NPN transistor acts as a controller switch which controls the speed of the fan by using the signal from the Arduino. The IN4007 Diode acts as a protection for the fan from being damaged. When the temperature exceeds the max temp the 5mm LED light glows. Working of the temperature based fan speed controller Circuit
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.
