Design And Construction Of A GSM-Based Fire Alarm And Emergency Control System

ABSTRACT

This project is titled design and construction of a GSM based automatic fire emergency alarm. This device is an electronics device that is stored in a building to detect the presence of fire accident. An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. The aim of this project is to design and construct a fire alarm for a building that will detect the presence of fire accident in a building using SMS Alert system, it uses LM35 Temperature Sensor and MQ2 for Smoke sensing and 16×2 LCD is used to display temperature and Smoke Level.

CHAPTER ONE

1.0                                                      INTRODUCTION

In modern society, it is impossible to imagine house or building without a fire accident detector. Modern houses require a continuous installation of fire detector. Not only industry, but also in the household. Take the case of a duplex that experience a fire accident without a detector that means everything in that building will get burnt even human beings. But in a case whereby fire alarm is installed that means everyone in that building will be alerted and also fire security bodies will also be informed for quick security action. The same thing can also happen to our offices and industries. In order to notify residence of any building in the presence of fire accident, a fire alarm system is used.

A GSM based automatic fire alarm and emergency system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is classified as either automatically actuated, manually actuated, or both. Automatic fire alarm systems are intended to notify the building occupants to evacuate in the event of a fire or other emergency, report the event to an off-premises location in order to summon emergency services, and to prepare the structure and associated systems to control the spread of fire and smoke.

1.2                                            STATEMENT OF PROBLEM

The Nigerian environment is considered to be hazards prone brought about by man-made and natural disasters due to its geographic circumstance which is exposed to catastrophic, floods droughts and fires. Based on the reports; devastations of these natural hazards and disasters including fires have increased in recent years. Our lifestyle of negligence and adapting to emerging technological solutions puts us at the risk of loss to fire and related occurrences as seen in markets, homes and other public places. The risk of fire occurrence is high especially during the dry season, Christmas and New Year celebration due to firecrackers. In the case where house fires are prevalent, it has effect to derail the economic growth, destroy social and physical capital including infrastructures, which resort to reallocation of ongoing programs to finance relief operations to fatalities and inhabitants and reconstruction efforts which diverts funds to social services. Fires are considered natural and man-made hazards.  This technology aimed at putting an end to these problems by alerting the owner of house at the starting point of fire accident via SMS and alarm.

1.3                                     AIM/OBJECTIVE OF THE PROJECT

The aim of this work is to construct a device that will detect the unwanted presence of fire. It detects the unwanted presence of fire by monitoring environmental changes associated with combustion  using SMS Alert system, it uses LM35 Temperature Sensor and MQ2 for Smoke sensing and 16×2 LCD is used to display temperature and Smoke. At the end of this work the following objectives shall be achieved:

1. Building a device that senses both the presence of fire and human being in a room
2. The student shall become conversant the lm35, MQ2, and ultrasonic sensor

• Shall also know how to interface the LCD with the microcontroller.

1.4                                           PURPOSE OF THE PROJECT

The main purpose of this work is to save life and property via using GSM based fire sensor.

1.5                                       SIGNIFICANCE OF THE PROJECT

• The primary advantage of a home fire alarm system is increased reliability and the ability to place alarms and bells exactly where needed. However, the reason most people have them is that they wanted a burglar alarm system and the cost of adding fire alarm features to a residential burglary system is relatively small.
• This device disconnects Electrical Supply as soon as Fire is detected.
• Sends Fire Alert SMS with Temperature and Smoke Level to Given number.
• Makes Loud Sound using buzzer to alert about fire. Uses Standard MQ2 Smoke Sensor and LM35 Temperature Sensor.

1.6                                              SCOPE OF THE PROJECT

GSM, Microcontroller Based Fire detection, it uses LM35 Temperature Sensor and MQ2 for Smoke sensing and 16×2 LCD is used to display temperature and Smoke Level, Over limit set points are set inside the program you can modify it as per your requirements, It Sends SMS when set limits are crossed through GSM modem that is attached to Serial Rxd and Txd Pins, Set your mobile number inside the code in Send SMS subroutine. It generates Sound When Fire is detected for alerting.

1.7                                      APPLICATIONS OF THE PROJECT

1. SMS based Fire Alarm system are very useful in remote locations where human interaction is limited. Such systems are useful in mines, industrial areas, factories etc.
2. Night Owl – We all know owls don’t sleep during night. SMS based Fire Alarm system helps to monitor locations and alert during fire that occurs in night time.
3. Quick Actions to shut down Fire – 90% of fire damages occur due to lack of early fire detection. A fire attack is usually silent and people will know about fire only when it has spread across a large area. SMS based Fire Alert system gives warning immediately to multiple mobile numbers and hence remedy actions can be taken quickly. This helps to prevent major damages and losses created by a fire accident.

1.8                                                         PROJECT ORGANISATION

The work is organized as follows: chapter one discuses the introductory part of the work,   chapter two presents the background literature review of the work,  chapter three describes the methods applied,  chapter four discusses the results and system test, chapter five summarizes the research outcomes and the recommendations
