The document presents a project on a thief detector system using a PIR sensor and GSM module. The system is designed to detect motion using the PIR sensor and send an alert message or phone call via the GSM module. It includes the objectives, design, equipment required, circuit diagram, program code, and results. The project aims to provide home security by detecting intruders and automatically alerting the user through a phone call when motion is detected by the PIR sensor.

2. Intrudaction
In today’s age of digital technology and intelligent systems, home automation
has become one of the fastest developing application based technologies in the
world. The idea of comfortable living in homes has since changed for the past
decade as digital and wireless technologies, are integrated into it. The main
concept behind the work is receiving sent Short Message Services (SMS) or
phone call and processing it further as required to perform several operations.
There are several terminologies that are used extensively throughout this paper
such as Global System for Mobile Communication (GSM), SMS, etc.

3. Objective
The GSM based intelligent home security system refers to the use of device
and information technology to control home features/systems (such as
windows, door etc.). Parameters to be controlled in any system could be very
simple/complex. These can range from single control of lighting through
complex computer/microcontroller based networks with varying degrees of
automation. Home security system is adopted for reasons of ease, security and
energy efficiency.

4. Design
Our project domain name is Thief detector system with GSM module and pir
sensor. For that we need to build a system that can take input as signal by pir
sensors and as output we get an alarm like phone call or SMS. For
implementation of coding part we use C and C++ programming and compiler.
Basically our project most priority goes to electrical instrument like PIR
monitor sensor, GSM modular, a power supply and a Mobile phone.

5. Equipment Require
1. PIR Sensors.
2. GSM Modular.
3. Arduino.
4. Wire.
5. Breadboard.

8. Program
#include <SoftwareSerial.h>
//Create software serial object to communicate with SIM800L
SoftwareSerial mySerial(3, 4); //SIM800L Tx & Rx is
connected to Arduino #3 & #2
int b = 8;
int state;
void setup()
{
//Begin serial communication with Arduino and Arduino
IDE (Serial Monitor)
Serial.begin(9600);
//Begin serial communication with Arduino and SIM800L
mySerial.begin(9600);
pinMode(b, INPUT);
}
void loop()
{
state = digitalRead(b);
if(state == HIGH)
{
delay(5000);
Serial.println(" barton ok");
call();
delay(500);
}
}
void call()
{
Serial.println("Initializing...");
delay(1000);
mySerial.println("AT"); //Once the handshake test is
successful, i t will back to OK
updateSerial();

9. Program
• mySerial.println("ATD+ +8801858587314;"); //
change ZZ with country code and xxxxxxxxxxx with
phone number to dial
• updateSerial();
• delay(20000); // wait for 20 seconds...
• mySerial.println("ATH"); //hang up
• updateSerial();
• }
• void updateSerial()
• {
• delay(500);
• while (Serial.available())
• {
• mySerial.write(Serial.read());//Forward what Serial
received to Software Serial Port
• }
• while(mySerial.available())
• {
• Serial.write(mySerial.read());//Forward what
Software Serial received to Serial Port
• }

10. RESULT
After connecting all of the component make sure that the all of devise get
enough power to run it. For that we need to enough power supplier. After
completing it if we put the hand on the PIR Sensor the alert message or call
will come to our phone. Given Fig 02 there is the pic of our project.
