This document describes a security alarm system that monitors a diamond in a museum using infrared sensors. The system can monitor up to 4 sensors and will light an LED and sound an alarm if a sensor is triggered, indicating unauthorized access. It also sends a message to a programmed mobile phone. The system is designed using an Intel 8052 microcontroller, infrared sensors, an LCD display, buzzers and a Bluetooth module. It provides effective security monitoring of restricted areas.

3.  Security is primary concern for every one. This Project describes a
design of effective security alarm system that can monitor the
diamond in a museum using IR sensors. A IR sensor is connected to this
system for visual indication of the safety of the diamond.
 This Project describes a design of effective security alarm system that
can monitor the diamond security with two different sensors. Unauthorized
access can be monitored by the status of each individual sensor and is
indicated with an LED. This security system works perfectly all the time
i.e., whether someone is present in the place or not.

4.  A maximum of 4 sensors can be connected to the burglar alarm. These
sensors need to have their contacts closed when in the inactive state (i.e.
Normally Closed). In addition, each sensor needs to have its tamper
connection wired as well. A power supply voltage of +5 VDC is
available for each sensor at the corresponding wiring terminals.
 When the alarm has been activated, the LED of the sensor that caused
the alarm will light up.The uniqueness of this project is not only alerting
the neighbors by siren, it also sends a message to smart mobile which is
already programmed into the system.

6.  An embedded system is some combination of computer hardware
and software, with either fixed or programmable capabilities, that
is specifically designed for a particular kind of application device.
 Embedded systems do a very specific task, they cannot be
programmed to do different things.

9.  The Intel 8052 is, single chip microcontroller (µC) which was
developed by Intel in 1980 for use in embedded systems.
 Microcontrollers are widely used in embedded systems products.
Microcontroller is a programmable device.

10.  A liquid crystal display (LCD) is a thin, flat panel used for
electronically displaying information such as text, images, and
moving pictures.
 Its uses include monitors for computers, televisions, instrument
panels, and other devices ranging from aircraft cockpit displays, to
every-day consumer devices such as gaming devices, clocks,
watches, calculators, and telephones.
 Among its major features are its lightweight construction, its
portability, and its ability to be produced in much larger screen
sizes than are practical for the construction of cathode ray tube
(CRT) display technology.

12.  The buzzers are offered in lightweight compact sizes from the
smallest diameter of 12mm to large Piezo electric sounders.
 The buzzer is connected to port 3 of the microcontroller.
Types of buzzers

13.  Bluetooth is a wireless
technology standard for
exchanging data over short
distances from fixed and
mobile devices, and building
personal area networks
(PANs).
 it was originally conceived as
a wireless alternative to RS-
232 data cables.

14.  A mercury switch (also
known as a mercury tilt
switch) is a switch which
opens and closes an electrical
circuit when it is tilted at
certain angles.
 When it is tilted, a small
amount of the liquid metal
mercury makes contact with
metal electrodes to close the
circuit.

15.  A panic switch is an electronic device designed to assist in alerting
somebody in emergency situations where a threat to persons or
property exists.
 The switch can be used to request emergency assistance.

16.  A light-emitting diode (LED) is a semiconductor device that emits visible
light when an electric current passes through it. The light is not
particularly bright, but in most LEDs it is monochromatic, occurring at a
single wavelength. The output from an LED can range from red (at a
wavelength of approximately 700 nanometers) to blue-violet (about 400
nanometers).
 An LED consists of two elements of processed material called P-type
semiconductors and N-type semiconductors. These two In this elements
are placed in direct contact, forming a region called the P-N junction. In
this respect, the LED resembles the most other type diode types, but there
are Important other differences between the light emitting diode and the
normal diodes.

17.  Infrared Flame Detector:
 Infrared (IR) flame detectors work within the infrared spectral
band. Hot gases emit a specific spectral pattern in the infrared
region, which can be sensed with a thermal imaging camera (TIC)
a type of thermo graphic camera.
 False alarms can be caused by other hot surfaces and
background thermal radiation in the area as well as blinding from
water and solar energy.
 A typical frequency where single frequency IR flame detector is
sensitive is in the 4.4 micrometre range. Typical response time is
3-5 seconds.

18.  An LDR (Light dependent resistor), as its name suggests, offers
resistance in response to the ambient light. The resistance
decreases as the intensity of incident light increases, and vice
versa. In the absence of light, LDR exhibits a resistance of the
order of mega-ohms which decreases to few hundred ohms in the
presence of light. It can act as a sensor, since a varying voltage
drop can be obtained in accordance with the varying light. It is
made up of cadmium sulphide (CdS).
 An LDR has a zigzag cadmium sulphide track. It is a bilateral
device, i.e., conducts in both directions in same fashion.

19.  Keil software:
 Keil compiler is a software used where the machine language
code is written and compiled. After compilation, the machine
source code is converted into hex code which is to be dumped into
the microcontroller for further processing. Keil compiler also
supports C language code.

21.  We conclude that main objective of this project is to develop an
embedded system to monitor the unwanted persons in the
restricted areas.
 It has been developed by integrating features of all the hardware
components used. Presence of every module has been reasoned out
and placed carefully thus contributing to the best working of the
unit.

22. .
 For the further development of this project we can do the
programming in such away if any intruder enters into the
restricted area directly the call or message will be
forwarded to concerned area police station.
 Automatically it will shutdown the premises if any
intruder enters into the restricted area.
