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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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. 

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.

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.

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.

.

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.
