Introduction:

These days pretty much everything is getting programmed for giving a superior encounter of life. Here and there individuals are too lethargic to even consider doing something. For instance if an individual is sitting in a room getting a charge out of a film or watching something different on TV. In the event that the room temperature expands, at that point the individual should stop the film and turn on the fan. It will upset the individual. So as to conquer this obstacle and to give a superior encounter the fan can robotized.

In this project a fan will be mechanized utilizing a temperature sensor. The temperature sensor will flag the fan. The speed of fan will increment or lessening as indicated by the adjustment in the room temperature. The temperature-controlled fan will make the framework vitality effective. The temperature-controlled fan will likewise be time productive.

Background:

Already the fans were controlled physically. The fan was turned here and there by killing the switch ON and. The speed of fan was likewise balanced physically by a controller. All these procedure was power expending and tedious. A few times the manual control of fan gets chaotic .To improve ones experience there was a requirement for changing this framework. To spare time and make the framework vitality effective there was a need to make another framework.

Components Details :

1. Arduino

2. Breadboard

3. Temperature Sensor

4. DC Motor (as a fan).

5. LCD Display.

6. Resistor.

Arduino:

Arduino Uno is a micro controller board based on the ATmega328P.It has 14 digital input/output pins (of which 6 can be used as PWM outputs. 6 analog inputs, a 16 MHz ceramic resonator (CSTCE16M0V53-R0), a USB connection, a power jack, an ICSP header and a reset button., It contains everything needed to support the micro controller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

Circuit and Implementation of the Project:

Working of the Project:

• When the simulation is started the LCD turn on and displays “Temperature

Controlled Fan”.

• Then the temperature sensor starts reading the room temperature.

• The LCD displays a message “Recording Temperature”.

• When the temperature sensor has read the room temperature the LCD displays the room temperature.

• The temperature is measured in centigrade.

• The baseline temperature is 18 degree.

• When the temperature is below 18 degree the fan is off.

• When the temperature increases then the fan turns on.

• If the temperature is more than 18 degree, the speed of fan is 20 percent.

• If the temperature is more than 21 degree, the speed of fan is 40 percent.

• If the temperature is more than 24 degree, the speed of fan is 60 percent.

• If the temperature is more than 27 degree, the speed of fan is 80 percent.

• If the temperature is more than 31 degree, the speed of fan is 100 percent.

lcd.println("Fan speed 60%");

delay(3000);

lcd.clear();

}

if(celsius>27&&celsius<=30)

{

analogWrite(fan,204);

lcd.println("Fan speed 80%");

delay(3000);

lcd.clear();

}

if(celsius>=31)

{

analogWrite(fan,255);

lcd.println("Fan speed 100%");

delay(3000);

lcd.clear();

}

delay(10);

}

Results:

Following targets are achieved
A temperature-controlled fan
This fan will save electricity.
The fan will not have to be turn on and off manually.
It will bring ease so that a person will not have to control it. The fan will adjust its speed according to the environment of the room.

Conclusion:

This temperature-controlled fan can be implemented physically in a home. It will bring an ease in life. It will contribute in home automation.This system can be improved further.A PIR Motion Sensor can be implemented along with the system. The PIR Motion Sensor will detect a person and then signal the system to work accordingly. It will make the system more efficient and will also contribute in less power use.
