This device detects an Intruder. By when there is a person passes or cut the light infrared. The system will clearly warn immediately, command give an indication through an alarm. Circuit diagram of this device uses an infrared sensor to sense intrusions. Infra red rays reflected from a static object will be in one phase, and the rays reflected from a moving object will be in another phase. The circuit uses this principle to sense the motion. The IC1 (NE 555) is wired as an astable multivibrator. The IR diode connected at the output of this IC produces infrared beams of frequency 5Khz. These beams are picked by the infrared sensor, photo transistor Q1. At normal condition, that is, when there is no intrusion the output pin (7) of IC2 will be low. When there is an intrusion the phase of the reflected waveforms has a difference in phase and this phase difference will be picked by the IC2. Now the pin 7 of the IC 2 goes high to indicate the intrusion.

CHAPTER ONE
1.0                                                        INTRODUCTION
Intruder alarm is designed to detect intrusion – unauthorized entry – into a building or area. Security alarms are used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders. Car alarms likewise protect vehicles and their contents. Prisons also use security systems for control of inmates.
Some alarm systems serve a single purpose of burglary protection; combination systems provide both fire and intrusion protection. Intrusion alarm systems may also be combined with closed-circuit television surveillance systems to automatically record the activities of intruders, and may interface to access control systems for electrically locked doors. Systems range from small, self-contained noisemakers, to complicated, multi-area systems with computer monitoring and control.

1.1                                         BACKGROUND OF THE PROJECT
The need for having home protection has always been there. But in the recent times, considering a dramatic rise in petty crimes like robbery and theft, the need has been more strongly felt to have a fool proof protection of the belongings and the family members. Home security has come a long way in the last few decades. It was in the hands of a guard who manually provided surveillance during nights in the earlier days, but it was not fool proof as it was only normal for him to have momentary lapse of concentration.
The guard was also susceptible to sleep at times. It was then that home alarm system based upon electronic circuits were developed which proved to be highly reliable and were appreciated by the people as they were relieved from constant monitoring of their homes.

1.2                                             OBJECTIVE OF THE PROJECT
This intruder alarm is wireless home monitoring devices to monitor and alert in case of a burglary attempt at that place – house or a commercial place. Our objective is to ensure security of property using our device.

1.3                                              PURPOSE OF THE PROJECT
This project proposes the development of security system for form houses and residential houses. 

1.4                                         SIGNIFICANCE OF THE PROJECT
This device gives an indication via alarm when an intruder trespasses. By when there is a person passes or cut the light infrared. The system will clearly warn immediately, command give an alarm.
This wireless alarm systems work on batteries and not electricity. Which means this device is effective during power-cuts as well.
Homes and commercial properties that have burglar alarm systems installed are at a lesser risk of being targeted by intruders and burglars. When infiltrators find out that you have an alarm system installed, they are persuaded to move away from your property. Even if they are not aware of its presence, the alarming sound will scare them off.
An alarm system alerts you when the property is unattended and invaded by thieves. These smart, easy to learn devices notify you when intruders attack your property while you are away or sleeping. Like any other security systems, alarm security systems also have a set of pros and cons. Below are various advantages and disadvantages of installing them on your residential or commercial site.
Appointing security guards or personally being there to protect the property 24/7 is practically not possible. These security systems provide round-the-clock protection against burglars and break-ins.

1.5                                                 SCOPE OF THE PROJECT
In an extremely mechanized word such as today’s it is necessary to make our life better, convertible and economical. This is the purpose for which the Electronic house is developed.
The project composed of the:

• Transmitter
• Receiver
• Seven segment counter

TRANSMITTER :The transmitter section is built around IC 555 (IC1),Ø which is wired as an astable multivibrator. It produces about 38 kHz frequencies. IR LED1 emits 38kHz modulated signals up to aØ distance of 4.6 metres (15 feet). The modulated IR beam from the transmitterØ continuously falls on the receiver section.
RECEIVER:  The receiver sensor TSOP1738 responds to 38kHz frequency. The modulated IR beam falling on receiver sensor TSOP1738 makes its output low. When somebody crosses the path of IR rays it senses this and its output goes high momentarily, which triggers the flip-flop. The IR transmitter and receiver units are mounted opposite to each other on the sides of entry door or gate.

1.6                                          APPLICATION OF THE PROJECT
This device is used in the following places as:

• Home Security Systems.
• Prisons Security.
• Vehicle Security.
• Broadband alarm monitoring.
•  Glass Break.
•  Property Theft Alarm

1.7                                              PROBLEM OF THE PROJECT
False Alarm: These security systems are prone to false alarms that involve the alarm ringing when anyone from your family enters the restricted area. Or there are instances when the alarm is triggered by itself without any reason
Expensive: Wireless intruder alarm systems are expensive to install. They require an initial investment, which includes equipment cost and installation.
Can be Stolen: Irrespective of the type of intruder alarm you have, it can be stolen from the site where it is installed. Wireless systems are comparatively easier to disconnect. Some intruder can easily disconnect the wired alarm systems.
