Ac Fan Speed Control With Pwm

DOWNLOAD ABSTRACT

AIM:

Design and Development of AC Fan Speed Control with PWM.

PURPOSE:

In many applications AC fans used. Especially for cooling applications like chillers, incubator cooling systems and many more. For cooling applications, heat should control according to requirement. To do this we should control AC fan speed. Here we are doing this with Arduino PWM. Here project title is AC Fan Speed Control with PWM.

DESCRIPTION:

This project includes three buttons, which are connected to Arduino digital pins. AC fan controlled by BT136 triac which is connected to Arduino digital pin.

WORKING:

Here we can control AC fan speed using Arduino PWM. PWM will vary based on buttons pressing at Arduino. We can increment and decrement speed values with buttons. Based on speed value PWM technique performed in Arduino code to regulate AC fan speed. There is stop button, using this we can OFF fan at any time. FAN speed information will display on 16X2 LCD display.
