PROJECT DESCRIPTION: This work, design and construction of a door circuit with alarm research material is a complete and well researched project material strictly for academic purposes, which has been approved by different Lecturers from different higher institutions. We made Preliminary pages ( use it to develop yours), Abstract and Chapter one ofdesign and construction of a door circuit with alarm visible for everyone, then the complete material on design and construction of a door circuit with alarm is to be ordered for. Happy viewing!!!
The main objective of this project was to ensure a proper security to building against theft or intruder. This device functions as a major security alarms used in residential, commercial, industrial, and military properties for protection against burglary (theft) or property damage, as well as personal protection against intruders . It is an electronic device that is connected to the battery or 5v power supply being installed in and gets activated automatically when someone opens a door and it blows an alarm.
CHAPTER ONE
1.1 INTRODUCTION
Door circuit with 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.
This device protects the door and gives a loud Alarm tone when there is an attempt of theft. This simple door opening alarm using hall sensor produces sound when someone opens the door. The circuit can be installed at a workshop, office or home for security purposes.
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, office or workshop.
1.2 OBJECTIVE OF THE PROJECT
The objective of this work is to design a device will automatically indicate when someone opens a door and it blows an alarm. This circuit is used to detect the opening of door.
1.3 SIGNIFICANCE OF THE PROJECT
- Saves time for searching door bell switch.
- Saves electricity.
- Enhances security.
- Saves manpower.
- This device can be used to detect when occupants of house left their door open.
1.4 PURPOSE OF THE PROJECT
This project proposes the development of security system for form houses and residential houses.
1.5 APPLICATIONS OF THE PROJECT
- The circuit can be used as a door bell by connecting the supply to a switch.
- With some modifications it can be used to produce different sounds.
- It can be used in the office
- Homes
- industry
1.6 LIMITATION OF THE PROJECT
- As the applied voltage is 5V, it cannot produce more sound.
- You can only use it for one doors.
1.7 SCOPE OF THE PROJECT
This door opening alarm alerts you of intruders. You simply need to fit a small unit including magnetic switch on each door frame and fix a magnet on the moving door such that the magnet aligns with the reed switch when the door is closed.
A separate unit incorporating the power supply, three LEDs and a buzzer is to be kept by your side inside your room. A three core ribbon cable from this unit goes to each door unit. One core goes to the positive terminal, second to the negative terminal and third to the output of the unit. When the door is closed, the reed switch terminals are shorted and the alarm does not sound.
