Daffodil International University Co-Supervised By

We would like to express our gratitude, Ms. Nasrin Akter, Lecturer, Department of CSE, Daffodil International University for giving us a good guideline for assignment through numerous consultations. We would also like to express our sincere thanks to all those who directly and indirectly guided us in writing this assignment. We would like to thank our entire coursemate in Daffodil International University who participated in this discussion while completing the coursework.

With the progress of innovation, the amount of electronic devices in our everyday lives has expanded to make our life more straight forward and easy. Such a need to build an all-encompassing Remote Framework that will effortlessly control each of these gadgets from a separation will not only reduce the versatile nature of handling the amount of gadgets at the same time with voice command through the mobile device, but also save power. Our project displays the general plan of Digital Home Automation (DHA) with minimal effort and remote framework.

Digital Home Automation Systems (DHAS) are produced with the gift of today's science, especially in the field of construction and visualization. Due to the progress of remote innovation, several different associations have been presented, for example, GSM, WIFI and Bluetooth. Each of the associations has its own particular details and applications.

Likewise, the majority of the current workstation/journal or mobile phone included in Bluetooth connection worked.

ANALYSIS OF THE SYSTEM

• System Definition
• Proposed System Features
• Lighting Switches On and Off: Lighting systems can be programmed to switch certain Lights on or off. We can do this in two ways
• Fan Switches On and Off
• TV/Computer/Air Conditioner
• LPG gas Leakage and Security system
• Gas leakage detector (Domestic)
• System Requirement
• FEASIBILITY STUDY
• Introduction
• Feasibility Study
• METHODOLOGY
• Preliminary Considerations
• System Design
• What Is Arduino?
• HC-05 Bluetooth Module
• AT89S51 Microcontroller
• MQ-6 Gas Sensor
• GSM Module
• Stepper Motor
• Arduino IDE

Automatic: This means that the fan can be set to switch on or off under certain conditions (for example at high or low temperatures). Alternatively, the fan can be set to automatically turn on when the temperature is high, or turn off when the temperature is lower. This means that the TV/computer/air conditioner can be set to turn on/off via voice commands using Google's voice recognition, and the TV/AC switch is controlled via Bluetooth.

The main objective of this part of our project is to sense the gas if it has accidentally leaked and then notify the user by calling his/her mobile using the gsm module. In order to manage the project workflow efficiently and for certain moments were set at the beginning of the project with predetermined timelines for the design, development, testing and documentation of all phases involved during the life cycle of this project. Daffodil International University 10 . iv) Operational: Assessing the operational feasibility of this project was a key factor in determining the methodologies used in designing, developing and deploying this project to work in a given environment.

In this way, with the end goal of this venture, some particular thought decisions were made about the type of stages, equipment segments, and activity method of the home computing framework. Prior to the actual plan for the task work, decisions were made to consider the selection of correct use steps and equipment segments. Of the currently available platforms: Arduino, Powerline, AT89S51 microcontroller, Bluetooth, Android Device, Infrared, GSM and Microcontroller; The Bluetooth module and microcontroller were found most suitable due to their low cost availability, reliability and simplicity when used for an individual control home automation system that my project work is on.

As illustrated in the block diagram in figure 4.1, when the HC05 receives the required signal, it communicates with the Arduino, the Arduino controls the relay state via an application and it in turn determines the state of the connected device, either on or off via voice control. Many of the hotels and restaurants do not keep any safety measures to detect gas leakage due to lack of. For teachers, this is favorable from the perspective of the Ready programming condition, so students who make sense of how to program in that condition will be fine with the look and feel of Arduino.

Open source and broad hardware - The designs of the Arduino sheets are released under a Creative Commons permit, so any circuit builders can influence their own version of the module to explore and improve it. Indeed, even generally impractical customers can assemble the breadboard variant of the module with the end goal in mind to see how it functions and save costs. The MQ-6 (Figure 4.7) can detect gas concentrations anywhere from 200 to 10,000 ppm. This sensor has a high sensitivity and fast response time.

This sensor Figure (4.7) comes in a package similar to our MQ-6 gas sensor, and can be used with the breakout board below. This motor is used to open the window of the house and the gas will be avoided.

DESIGN AND IMPLIMENTATION

• Arduino Code Explanation Coding Part of Home Automation
• AMR_Voice Software
• Gas leakage system
• Real life problem and implementation
• Student injured in Mymensingh gas explosion dies in March 29, 2018

For example: when we say "lights on", then our light has been turned on, or when we say "lights off", turn off the lights. We can link the Bluetooth module to the Arduino using an arrangement of jumper wires and a connector. Note: Do not connect RX to RX and TX to TX on Bluetooth and Arduino.

To issue voice commands we need an Android device for the installation of AMR_Voice control and after installing the software we follow this procedure according to the image. In our project we have a gas leak system where the gas is automatically detected when there is a leak and therefore a call is made via the GSM module to warn the user. In this overview (Image: 5.5), we can see that after powering on, if the gas sensor distinguishes the gas sensor, the GSM module associated with Arduino when there is gas in the room, the window opens and closes naturally and tries to release gas to expel the kitchen or the kitchen. room and if the gas leakage rate is high at that time, please call the customer number and tell it through the bell.

The red light will be on when the gas sensor detects gas and the window is open trying to evacuate gas, and the green light will be on when the room is secured against gas leakage. A gas cylinder exploded on the third floor of RS Tower, a six-storey residential building in Jamirdia Masterbari neighborhood of Bhaluka, killing Shaheen's classmate Towhidul Islam Topu on the spot. Engineering and Technology, succumbed to his injuries at around 11 pm at Dhaka Medical College Hospital, said Bacchu Miah, Sub-Inspector of DMCH Police Outpost.

In this explosion, five members of a family, including three children, are undergoing treatment at the burn unit of Dhaka Medical College and Hospital after sustaining burn injuries in an explosion caused by "gas line leak". The incident took place on the ground floor of a five-storey building at Shampur around 3 am.
