Home security system is needed for occupantsconvenience and safety.

The system is a wireless home network whichcontains a GSM gateway.

Two kinds of wireless security sensor that areinfrared security nodes and alarm nodes.

This design and its implementation are of low

cost, low power consumption and GSM(GlobalSystem for Mobile Communication) based.


3/13

Security is a basic need of all living creature. So thisfulfill this purpose with low implement cost.

As the security needed for money , jewellery & forimportant documents in different fields(like offices,houses etc.). It also fulfill this requirement .

Mainly designed for home & offices but also

beneficial in a large scale industries & buildings.

NEED OF IT AND WHERE..?

PIC16F877A Controller

GSM(Global System for Mobile Communication)modem

Sim card for GSM modemPIC development kit

IR sensors

BuzzerPower supply

Destination mobile (Receiver)

HARDWARE REQUIRMENTS :-


5/13

MicroC pro complier

This complier is basically used for PIC family

It converts the c program body in HEX file

It is user friendly because of its large library set

It is compatible with a lot of devices

Embedded C programming

SOFTWARE REQUIRMENTS :-

BLOCK DIAGRAM :-


8/13

IR SENSOR :-

Infrared sensors

Combination of 2 type of diodes.

Transmitter- LED Receiver- photodiode

Range 5 m(approx.)

Signal 1 transmitted at no interrupts

Signal 0 transmitted at interrupts


9/13

MICROCONTROLLER :-

Contains 40 pins.

Have EEPROM on chip(256 bytes)

It have predefined libraries

HEX file is burnt on chip by using flash magic(burner)

5 ports(A,B,C,D,E)

Serial comm. by UART

Operating freq.-20MHz

35 instruction set


10/13

GSM MODEM :-

It works on a baud rate of 9600

It contains transmitter & receiver

It communicate serially

Operating voltage is 5V

Have large number of AT commands for different purpose

Work similar as our mobile phone


11/13

C PROGRAM BODY :-

void main(){UART1_Init(9600);Delay_ms(500);

TRISA=0x01;

if(PORTA==0x01){UART1_Write('A');Delay_ms(500);

UART1_Write('T');Delay_ms(500);

UART1_Write('+');Delay_ms(500);UART1_Write('C');Delay_ms(500);

UART1_Write('M');Delay_ms(500);


12/13

UART1_Write('7');Delay_ms(500);UART1_Write('3');

Delay_ms(500);UART1_Write('1');
