Automation SystemAutomation System

Household electrical devices operate on minimum 220V

AC power supply

RELAY - Allows low power circuit to switch a

relatively high Current/Voltage ON/OFF

Relay coils are designed to operate from a particular

voltage often its 5V or 12V

ULN2803 – driver IC contains NOT gates

4. GSM Module4. GSM Module

GSM Modem

Acts as a mobile phones

GSM modem supports “ Hayes commands” also known as AT

commands

GSM modems are a cost effective solution for sending

receiving SMS

Serial CommunicationSerial Communication

• Process of sending data one bit at a time

• Baud rate

• Start Bit

• Stop Bit

• SBUF Register

• RS232

5. Interfacing5. Interfacing

GSM modem is connected to PC through serial

communication

DB9 cable(9 pins) is used for serial communication

3 pins(receive, transmit, ground) are sufficient for connecting

to the microcontroller

RS232 communication

GSM Modem is connected to Max232

6. Controlling Devices from Smart Phone6. Controlling Devices from Smart Phone

Electrical devices are connected to the corresponding relays

Sensors are placed at appropriate places

Target number can be changed dynamically by the user

User can switch the devices either individually or collectively

Application automatically starts and alerts the user for any

security threat detected at the target site

ConclusionConclusion

The proposed home automation system provides a reliability

and flexible to the user to control both electrical and

electronic devices

This work is accomplished through the integration of widely

available devices, components and Software

Future WorkFuture Work

The GSM communication used in the system may be replaced

by 3G communication

It will enables the application to stream live video for

surveillance purpose

Multiple communication techniques can be used, Bluetooth

can be used when the user is near the devices and GSM can be

used when the user is out of Bluetooth coverage
