6.1 Conclusion
The Project contributes in design and implementation of IOT Based hazardous gas leakage detection system. We have proposed a method for real time gas leakage detection system that categorizes the content of the feedback as gas leakage and help to sense the gas leakage from gas pipe. the feedback whether it is positive and negative that is gas leakage is there or not. In this approach, the sensor are used to detect the gas from where the gas is leaking and it give message to the Customer or users. It is used to increase the safety and monitoring and proper maintainence. Gas leakage is one of the most common reasons for fire breakouts in building,hotels,hospitals. A leakage can be turns out to be cause of terrible accident particularly in closed buildings,hotels,hospitals. Many of the hotels and restaurants do not keep any security measures to detect gas leakage due to lack of enforcement of standards and pre-assumption that installing such precautionary systems will be more costly. This is a gas leakage detection project based on Arduino UNO. The low cost project uses MQ6 gas sensor which can be calibrated to detect leakage levels based on surroundings and it is inexpensive compare to precautionary system. The installation generates a sound alert using buzzer on detection of a dangerous leakage. The project utilizes the 434 MHz RF module so the alarm can be installed anywhere within the building,hotels and hospitals and even multiple alarms can be installed within a building, hotels,hospitals. There is alarm which is automatically goes off when the sensors does not detect any utensils on burner. Using Infrared Sensor it also monitored the wastage of gas
The gas monitoring system is based on both wired and wireless sensor technology. Leakage of gases may cause fire accidents and hazardous condition is the major issue nowadays. The leakage of every gas is monitored through gas monitoring system to avoid such condition. This type of monitoring system can be helpful in hospitals, homes, hotels and many commercial places. Nowadays gas leakage and gas detection is a major problem in our daily lives. Also gas wastage is a major issue that needs to be countered.GAS is highly flammable and can inflict damage to life and property.To avoid such situations,a considerable amount of effort has been devoted to the development of reliable techniques for detecting gas leakage.As knowing about the existence of a leak is not always enough to launch a corrective action,some of the leak detection techniques were designed to allow the possibility of locating the leak.Our aim is to reduce the risks In gas pipe using Internet of Things.The main aim is to propose the design and construction of an SMS based Gas Leakage Alert System. Gas sensor are used to detect gas leakages in a pipe.With the help of an infrared sensor the issue of gas wastage is also monitored. An alarm goes off whenever the sensor doesn’t detect any vessel over the burner beyond a particular time period.

Nowadays the safety is more than anyother things. Safety plays a major important role in todays world. Our system IOT based Hazardous Gas Leakage detection System is used for prevent from fire breakouts. A leakage can be convert in a terrible accident Particulary in office place or any work or educational place.MQ6 gas sensor is used for LPG and butane In MQ6 there are A and B pins which are interchargeable. MQ6 gives output in Analog and Digital form
Digital output get by setting threshold value using the potentiometer. using infrared sensor it is used to sense the vessels are on flame is present or not it also useful from wastage of gas. like flame is on but there is no utensils present on it. If there is any gas leakage or gas wastage it is monitored and it sends the SMS to the authorized person via GSM. MQ6 sensor is used for LPG and butane gas. using this system we can monitored and controled all the hazardous gas leakage detection. Gas is highly flammable and can inflict damage to life and property.To avoid such situations,a considerable amount of effort has been devoted to the development of reliable techniques for detecting gas leakage.

To create successful innovative business and succeed with new product or service, company must listen to customer feedback. Customers can help to develop a better product, to provide a better service, to bring purpose to the product or valuable service offering, to tell how they really feel about a product or service and provide the best advice. By having customer insight, listening to customers and making them happy, company can create strong and long-term relationships with customers getting lifetime revenue, because people do business with people they like, know and trust. Nowadays, most of the people are using Gas cylinders so any hazard can happen anytime Which can be dangerous. Nowadays people are careless and they don’t or forget to close gas connection when they finish with there work, so this will help them to know when there is a gas leakage. Using Infrared sensors it detect there is any vesssels on gas using this system there can be no gas wastage and it monitored and controlled by the sensors. If there is any gas wastage the SMS is sends to the authorized Person via GSM.

Importance of project and Motivation:
There are threats because of the gas pipe, Because detecting it’s leakage is very difficult compared to cylinders. So this project helps you to detect any hazard gas leakage in work or educational places like homes, Offices, Hotels, Hospitals. With the help of MQ6 gas sensor it is used to detect from actually where the leakage is starting, so it can protect from a any hazard going to happen in future. It gives an alert Meassage to the client or customer through SMS or email only the authorized person.

Scope of the Project:
Safety plays a major role in today’s world and it is necessary that good safety systems are to be implemented in places of education and work. This work modifies the existing safety model installed in industries, hotels, hospitals and this system also be used in homes and offices. The main objective of the work is designing Arduino uno and MQ6 gas sensor based toxic gas detecting and alerting system. The hazardous gases like LPG and propane were sensed and displayed each and every second in the LCD display. If these gases exceeds the normal level then an alarm is generated immediately and also an alert message (SMS) is sent to the authorized person through the GSM. If there is any leakage in pipe then also it sends the message to the authorized person through GSM.


The purpose of this project is to prevent the user from fire which can happen from gas leakage in pipe when transmitter switch is ON. ARDUINO start loading all the libraries and intialize the LCD display. It also set the sensitivity level and user can increases the sensitivity level. using senstivity value is used for set the reference value. program code on Arduino is used to keep the all track of Analog value from MQ6 gas sensor.

Chapter3 – Analysis and Planning
3.1 Introduction
Analysis is the third phase in software development lifecycle which aims in finding the requirements for the project which we are going to implement. Analysis means to understand the business needs and processes so that the project we implement becomes efficient. In system analysis we consider what the system will need to take into consideration all the points so that the stakeholders will have the right model built That signifies to collect the requirements which reflects the stakeholders expectations. So in this phase we spent considerable amount of time talking with he customers and understanding their requirements. In short we can say that analysis phase means conquering requirements and analyzing them. So in analyzing requirements we create the deadline and consider various ways to achieve it and hence the requirements are considered formal requirements. There are several activities that must occur within the analysis phase:
Gather Information
Define the new system’s requirements
Build prototypes for the new system
Prioritize requirements
Evaluate alternatives
Meet with management to discuss new options
Design phase means making the model of the system to be built which deals with making user interface, system interface, backend of the project and also dealing with security issues. So the main motive behind this phase is to make the model which is tested to check if the system meets the stakeholders requirements as per elicitated and to make the system flexible and reliable. Some of the activities that need to take place during the design phase are:
Design the application
Design and integrate the network & Hardware
Design and integrate the database
The planning phase deals with finding out the scope to determine the outline of project, activities and actions and tasks involved. The deadline of the project is decided and also the estimated cost is negotiated between the stakeholder and the project manager. This phase only decides what will be the estimated risk or threat involved in the project. Accordingly the risk management plan is decided so it will deal with how the risk will impact the project and what should be done to reduce or avoid the risk. There are three points which are avoidance, correction and prevention. Prevention and Avoidance are pre-risk factors which occurs before the project is implemented and Correction is the post-risk factor which needs to be corrected after risk occurs in the project. Also this phase analyses the quality which the project should deliver and for that the quality plan is decided. So after this phase the project is planned completely and ready to be executed in further processes.

3.2 Product Backlog or Sprint backlog:
Backlog is a overview of the list of the task or features which the project team needs to follow so that the project deadline can be efficiently met. The items which are put in the backlog must meet the project requirements and should follow certain norms while in the backlog. If the item does not comply to the project goal then the item needs to be removed from the backlog and while the project implementation if the item is found to be a necessary part in project then needs to be added in the backlog but only once a day. We can say that as the project changes the items in the backlog will also change. Backlog in all defines the authoritative source from where the project manager should assign the tasks to the team members.

Product or sprint backlog is part of the scrum methodology which defines the items to be considered while implementation of project. Product backlog doesn’t mean that the team needs to do the particular task in stipulated time but will be pulling the items from the backlog to assign it to team as there exist enough space in backlog to enter other items. Product owner starts with considering two R i.e. roadmap and requirements. Roadmap provides the point to be followed while implementing and requirements specifies the resources required for the project. So the user stories are included in the backlog so as to identify what exactly the user is supposed to do and in what duration.

For IOT based Hazardous gas Leakage Detection Sysem the items which we will put in the sprint backlog are as follows:
As a project team member , I need to find the project and its domain so that I can find its scope. 1.Decide project title
2.Decide project scope
3.Detail project domain 10 days
As a project team member , I need to research about the project so that I can do the study and perform survey on it. 1.Perform feasibility study
2.Perform literature survey 16 days
As a active team member , I need to discuss the project with my guide so that I get clear idea about how the project needs to be completed and its current status. 1.Report to guide and discuss the project 4 days
As a project team member , I need to research about the project tool and sample data so that I can use that tool and implement the project based on the sample data. 1.Research on project tool
2.Finalize project tool
3.Research on project sample data
4.Finalize sample data 18 days
As a project team member , I need to research about the algorithm so that I can use that algorithm ; Hardware for the project. 1.Research the algorithm ; Hardware
2.Finalize the algorithm ; Hardware 5 days
As a project team member , I need to implement the project and perform testing so that I can debug the errors encountered in project. 1.Implement the project
2.Perform testing 5 days
3.3 Project planning (Resources, Tools used, etc.):
Planning the project provides the entire pathway from the initial stage till the final stage- how the project should proceed so that the deadline of the project can be accurately met.

Resources which we are using in our project are as follows:
Sample data for analyzing
ARDUINO is used as Hardware
MQ6 gas Sensor and Infrared Sensors are used.

Tools which we are using are used for classifying the data and then using that data and then cluster it using any of the tool.

3.4 Scheduling (Time line chart or Gantt chart) according to sprint backlog:
Timeline chart defines the date-wise assignment of the systems implementation so that proper schedule can be maintained and followed b the project team. All the items in the sprint backlog is pulled out from the backlog according to the time wise scheduling of the items and allocated to the project team members.

3.5 Summary
According to the software development lifecycle it canbe said that the analysis and planning part can form a barrier and impact the entire project plan if not followed properly. Therefore proper planning is required for the project to be completed properly. Proper planning is nothing but understanding the stakeholder requirements and then planning the implementation phase for the same.
