INTRODUCTION

What is home automation?

What can home automation do?

Where can you control it from?

INTRODUCTION

How does it work?

Automated homes are usually called smart homes, digital homes or intelligent environments.

PROBLEM STATEMENT

Wastage in energy consumption.

Wastage of finance (electricity bills).

Inconvenience.

AIM

The aim of this project is to develop an intelligent device for controlling and monitoring of the lighting system and the cooling system in the home.

OBJECTIVES

To design an automated system that will have the

ability to be controlled and monitored from a PC, use

of timer, temperature and light sensors.

To use a computer to turn on and off a light, as well

as to turn on and off a fan.

SCOPE

• The automation will be based strictly on

• Controlling and monitoring of lighting system.

• Controlling and monitoring of cooling system.

LITERATURE REVIEW

Brief History of home automation As far back as the 20th century due to

introduction of electricity.Emergence of electrical home appliances began

between 1915 and 1920.Home automation rose to prominence during the

1990s.

Some existing designs include:

Use of remote controlGSM based home automation system

LITERATURE REVIEW

Use of voice commandBluetooth based home automation systemInternet based wireless home automation system

Home automation communication protocols includes:

• X-10

• ZigBee

• Z-wave

PROJECT METHODOLOGY

Study the control unit:MicrocontrollerLight and temperature sensing unitRelay switching unit.

Come up with the hardware design. Simulate the circuit and troubleshoot(if need be) Come up with the software design:

Programming in C language.

Debug the programming codes and troubleshoot (if need be).

PROJECT METHODOLOGY

Burn the program into the microcontroller via the Programmer.

Carry out the actual construction.Carry out tests on the entire circuitry.

PROJECT METHODOLOGY

Light Sensing Unit

MicrocontrollerUnit

SwitchingUnit

Temperature Sensing Unit

Load

ComputerSystem

EXPECTED RESULT

At the end of this project, the developed intelligent device should be able to;

Control all the lighting system in the home using• Timer• LDR• PC

Control all the fans in the home using• Temperature sensing unit

• PC

Monitor and control the state of all the devices from anywhere using

• PC

CONCLUSION

In conclusion, if the above methodology is followed and carried out correctly, then all the afore mentioned objectives will be achieved.
