GSM Based Home Security System -abstract,report

GSM Based Home Security System

Abstract

Home security has been a major issue where crime is increasing and everybody wants to take proper measures to prevent intrusion. In addition there was a need to automate home so that user can take advantage of the technological advancement in such a way that a person getting off the office does not get melted with the hot climate.

Introduction

The project is aimed at developing the security of Home against Intruders , Gas Leak and Fire . In any of the above three cases any one met while you are out of your home than the device sends SMS to the emergency no provided to it.

The report consists of a background into the area of 8051 microcontroller and mobile communication, how they are interfaced to each other and AT (Attention) commands set used in communication.

HARDWARE USED

1. AT command supporting GSM mobile phone.

2. 89S52 Microcontroller

3. Max 232 IC.

4. Relays

5. Relay driver IC ULN 2803

6. Voltage regulator 7805.

7. Diode IN4007

8. GSM Phone

9. LPG Gas Sensor

SOFTWARE USED

1. Keil u-Vision 3.0

Keil Software is used provide you with software development tools for 8051 based microcontrollers. With the Keil tools, you can generate embedded applications for virtually every 8051 derivative. The supported microcontrollers are listed in the µ-vision

2. PRO51 Programmer Software

THEORY OF OPERATION

In this project we interfaced 8051 microcontroller with Motorola’s C168 GSM mobile phone to decode the received message and do the required action. The protocol used for the communication between the two is AT command.

The microcontroller pulls the SMS received by phone, decode it, recognizes the

Mobile no. and then switches on the relays attached to its port to control the appliances. After successful operation, controller sends back the acknowledgement to the user’s mobile through SMS.

AT-Command set

The following section describes the AT-Command set. The commands can be tried out by connecting a GSM modem to one of the PC’s COM ports. Type in the test-command, adding CR + LF (Carriage return + Line feed = \r\n) before executing. Table gives an overview of the implemented AT-Commands in this application. The use of the commands is described in the later sections.

A BRIEF INTRODUCTION TO 8051 MICROCONTROLLER:

When we have to learn about a new computer we have to familiarize about the machine capability we are using, and we can do it by studying the internal hardware design (devices architecture), and also to know about the size, number and the size of the registers.

A microcontroller is a single chip that contains the processor (the CPU), non-volatile memory for the program (ROM or flash), volatile memory for input and output (RAM), a clock and an I/O control unit. Also called a "computer on a chip," billions of microcontroller units (MCUs) are embedded each year in a myriad of products from toys to appliances to automobiles. For example, a single vehicle can use 70 or more microcontrollers. The following picture describes a general block diagram of microcontroller.

89s52: The AT89S52 is a low-power, high-performance CMOS 8-bit microcontroller with 8K bytes of in-system programmable Flash memory. The device is manufactured using Atmel’s high-density nonvolatile memory technology and is compatible with the industry-standard 80C51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory pro-grammer. By combining a versatile 8-bit CPU with in-system programmable Flash on a monolithic chip, the Atmel AT89S52 is a powerful microcontroller, which provides a highly flexible and cost-effective solution to many, embedded control applications. The AT89S52 provides the following standard features: 8K bytes of Flash, 256 bytes of RAM, 32 I/O lines, Watchdog timer, two data pointers, three 16-bit timer/counters, a six-vector two-level interrupt architecture, a full duplex serial port, on-chip oscillator, and clock circuitry. In addition, the AT89S52 is designed with static logic for operation down to zero frequency and supports two software selectable power saving modes. The Idle Mode stops the CPU while allowing the RAM, timer/counters, serial port, and interrupt system to continue functioning. The Power-down mode saves the RAM con-tents but freezes the oscillator, disabling all other chip functions until the next interrupt


The hardware is driven by a set of program instructions, or software. Once familiar with hardware and software, the user can then apply the microcontroller to the problems easily.

The pin diagram of the 8051 shows all of the input/output pins unique to microcontrollers:

The following are some of the capabilities of 8051 microcontroller.

ü Internal ROM and RAM

ü I/O ports with programmable pins

ü Timers and counters

ü Serial data communication

The 8051 architecture consists of these specific features:

§ 16 bit PC &data pointer (DPTR)

§ 8 bit program status word (PSW)

§ 8 bit stack pointer (SP)

§ Internal ROM 4k

§ Internal RAM of 128 bytes.

§ 4 register banks, each containing 8 registers

§ 80 bits of general purpose data memory

§ 32 input/output pins arranged as four 8 bit ports: P0-P3

§ Two 16 bit timer/counters: T0-T1

§ Two external and three internal interrupt sources Oscillator and clock circuits.

  41. The Chromebook obviously still requires these updates but they are managed in a very different way.

    The Chromebook is also sleeker and includes a more vibrant screen.

    The Samsung Chromebook is essentially a laptop that can only surf the internet and run apps.

  42. Only use your AC or Heater if it is absolutely necessary.
    The heat from the air moves into the cooled refrigerant.
    The Sewing Kit found at RHL is a great buy found for under $5.

  43. There is always a case to be made for a larger monitor to better enjoy the web, and
    the Ben - Q EW2420HD is certainly on my list for combining two HDMI ports,
    full HD (I have no time for HD-ready devices), an attractive bezel, and a price
    on the right side of $300. t have the benefits of an ebook reader (like reduced eye strain and long battery life),the i - Pad is
    in color and has a lot more functionality as a tablet (since
    it is really like a small computer). When
    spending $200 dollars on anything, it gets hard to
    complain about the shortcomings.

  44. Unfortunately these more compact designs have come at a great cost and have become far more susceptible to any kind of a liquid spillage.
    1: The $2,250 Swarovski-studded 32GB i - Pad, 5 Ridiculously Expensive Apple
    Gadgets You Won't Believe Are Real, and $20,000 Diamond Studded Apple IPad, the Most Expensive IPad Yet. It was a great investment and I found that it's better to not sweat the
    small stuff.

  45. And powering its various affairs will be the dual core Nvidia Tegra 2.
    1 feels excellent within the hand not like the Motorola Xoom and the Acer Iconia A500.
    1 is also known as Tab 750 and expected to be priced at Rs.

  46. Such addition shall greatly improve specific location detection
    typically, in addition to detecting location distance relative
    to other objects. This phone feels just as solid in hand as any other phone you will hold this year.
    It runs in very smooth and customized way to keep its users satisfied.
