ABSTRACT
As we know, security has been major issue in today’s scenario. Fire accidents are on increasing day by day. Here, we are talking about those accidents that are being occurred due to combustible gases, i.e., LPG, CNG. Frequently we hear, explosion in cylinder of household and vehicles. Several people have been injured and some got dead. So we are making this project for security purpose that will detect combustible gases and alert candidates. Now a day’s, propane gas leakage detector’s comes in the market with the propane sensor that only senses any gas leakage and sends a SMS to the emergency no. provided to it and alerts the user via audio or visual indications while we are on a project in which we are using a stepper motor also in addition to the normal propane Gas leakage detectors which helps in turning off the switch when there an emergency in our absence. In this paper, we are working on propane gas leakage detector. The sensor we are using here has excellent sensitivity combined with a quick response time. The sensor can also sense iso- butane, propane, LNG and cigarette smoke. The report consists of a background into the area of 8051 microcontroller and mobile communication, how they are interfaced to each other and AT commands set used in communication.

1.0 INTRODUCTION
1.1 BACKGROUND OF THE STUDY
With the development of world, the technology is enhanced day by day with the realistic projects and efficient work. In this project we are using MQ-6 semiconductor sensor to detect propane gas leakage. This sensor has lower conductivity in fresh air. When target combustible gases exist, the sensor conductivity is higher along with gas concentration rising. Basically, conductivity of this sensor depends upon concentration of the gas so it may detect not only combustible gas but also smoke, butane, isobutene, liquor. We can conjointly use it as a liquor tester. If the propane sensing element senses any outflow from storage then the output of this sensing element goes low. This low signal is monitored by the microcontroller and it will establish the gas outflow. Currently, the microcontroller turns on LED and Buzzer. Once few milliseconds delay, it conjointly activate fan for throwing gas out and continue send messages as “PROPANE GAS LEAKAGE” to your mobile no. subsequently the stepper motor turns off the switch of the cylinder. The proposed system discusses the development a GAS leakage detectors which composes of audio, visual and SMS alert system.
1.2 Problem Statement
Propane gas leakage leads to various causality resulting into both financial loss as well as human life. In human’s daily life, environment plays a vital role in health issues. The risk of fires, suffocation, explosion all are based on their physical properties such flammability, toxicity etc. The number of deaths figures due to explosion of gas cylinders has been increasing in recent years. The main reason for such explosion is due to sub- standard cylinders, worn out regulators, old valves and lack of awareness using gas cylinders add to risks.
1.3 Hypothesis/Research Questions
Research Hypotheses
H1: There is a significant relationship between fire accident and gas detector
Research Questions
- What is the importance of gas detector in a building?
- Is there any disadvantage of using gas detector?
- What is the operating principle of a gas detector?
1.4 Aim and Objective of Study
The main aim of this work is to design a GAS leakage detectors which composes of audio, visual and SMS alert system. The device can be used to detect propane gas leakage. The objectives are:
- To design a portable gas sensor
- To increase home security
- To interface MQ-6 Gas sensor, GSM module with microcontroller
1.4 Significance of Study
Propane gas detectors can be used to detect propane gas leakage. This type of device is used widely in industry and can be found in locations, such as on oil rigs, to monitor manufacture processes and emerging technologies such as photovoltaic. They may be used in firefighting. This study will help the student involve in this project and all the reader of the work to understand how to employ gas detector to prevent propane gas leakage and fire.
1.5: Scope of Study
The scope of this work focused on propane gas leakage detector built with gas sensor that only senses any gas leakage and sends a SMS to the emergency no. provided to it and alerts the user via audio or visual indications while we are on a project in which we are using a stepper motor also in addition to the normal propane gas leakage detectors which helps in turning off the switch when there an emergency in our absence. Gas Sensor (MQ-6) module is useful for gas leakage detection (in home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol. Due to its high sensitivity and fast response time, measurements can be taken as soon as possible. The sensitivity of the sensor can be adjusted by using the potentiometer. All of this sensor is used for a wide range of applications and can be found in industrial plants, refineries, waste-water treatment facilities, vehicles, and homes.
- Limitations of Study
- This device requires steady power supply for effect operation. That means that it will become inactive if the mains power supply fails or the battery goes low.
- The Sensor requires quarterly calibration and do not have a long life.
