1 INTRODUCTION

Fire accidents and gas handling represent serious

threats to human life and property. Many mainstream

monitoring methods today rely on manual

interventions that may slow down and be ineffective

in emergencies. Therefore, the work on this project is

aimed at developing an IoT-based gas leaf and fire

detection system with Arduino UNO, Alleys, Fire

Brigade Sensor, Summer, DC Fan, Servomotor, Water

Pump, and SIM800 modules. The system performs

actual monitoring of gas concentration and fire

hazards, triggers alarms, and performs safety

measures accordingly. When a gas leak is recognized,

the buzzer sounds, the DC fan is turned on and

ventilation is opened by the servo motor.

Additionally, SMS notifications are sent to the user

via the SIM800 module. Therefore, notifications are

guaranteed in real-time. The water pump is turned on

by the fire. The combination of IoT and automation

will help the project improve the safety of residential,

industrial, and commercial spaces, minimize risks,

and promote timely responses without human

intervention.

3 PROPOSED SYSTEM

The IoT-based gas leaf and fire detection system aims

to be an automated real-time security concept for

implementing gas leak detection and fire service

associations. The system includes a combination of

Arduino UNO and alleyway interface (MQ-2), flame

sensor, summer, DC fan, servo motor, water pump,

and SIM800 module. The alarm system (Summer)

opens the ventilation outlet via a servo motor to turn

on the fan and hand over gas when the alley sensor

detects the gas mirror to a minimum. Send an SMS

alarm to the user via the SIM800. This means that

users will be noticed immediately. If flame

recognition occurs through the flame sensor, the

water pump will start. Industrial and commercial

institutions.

4 METHODOLOGY

The methodology of the Arduino UNO-based gas

clever recognition system includes a combination of

various components to facilitate monitoring,

detection, and automated actions in real time. The

system starts from an alleyway, identifying leaks and

sending signals to the Arduino Uno -microcontroller.

In the event of a gas leak, the Arduino triggers a

buzzer to notify the user, indicating that the GSM

module (SIM800) sends an SMS alarm to a pre-

programmed contact. At the same time, the DC fan is

turned on, and the surface and diluent gas

concentration. When the fire sensor captures the

flame, the Arduino operates the servo engine to close

the gas valve to stop another leak and switch the

water pump to extinguish the fire. The system is

programmed to automatically operate to respond

quickly to gas leaks and fire threats. Arduino always

pursues sensors and adjusts the actuator. This

provides a powerful and stable solution for the

detection of gas leaks and emergency responses. This

approach uses IoT functions for remote notifications

and combines several security measures to maximize

user security and reduce risk.

security of residential, industrial, and commercial

buildings. Compared to traditional fire and gas safety

5 SYSTEM IMPLEMENTATIONS

5.1 Hardware Requirements

5.1.1 Gas Sensor

Generally, the valley presents four pens on an

Arduino board. On this board, two send performance-

aware data, one sends it to the Arduino UNO. This is

a very reasonable and effective semiconductor alley

module with analog and digital outputs. This module

uses MQ2 smoke and flammable alleys to recognize

gas. No external components are required. The VCC

and floor needles simply need to be connected and

ready to go straight away. Thresholds are defined in a

simple configuration via potentiometers. The MQ2's

smoke and flammable alleyways can easily connect

to any microcontroller, including the Arduino.

Figure 2: Gas Sensor.

5.1.2 Servo Motor

Servo motors are small and accurate rotary drive

elements for controlling the angular position, speed,

and acceleration of mechanical elements. It consists

of a DC or AC motor, a position search device, and a

steering circuit. These are mostly used when precise

movement control is required, such as in robotics,

automation, and aviation systems. A unique feature of

servo motors is that they can be converted to a

specific angle determined by the input signal.

Controls the position of the actuator via pulse width

modulation or PWM signals that specify the angle the

engine needs to rotate. In gas and leak recognition

systems, the servo engine controls the opening and

closing of the valve that unlocks the gas line when a

leak occurs. Their reliability, efficiency, and

smallness make them perfect for this application.

5.1.3 Processing Board

This is a microcontroller that typically has a user

development environment that compiles and provides

programs for the microcontroller. Arduino boards are

used in detail by enthusiasts, students, and experts to

develop interactive projects and prototypes in a

variety of fields, including robotics, home

automation, wearables, IoT applications, and more.

The beautiful thing about the Arduino platform is

based on a user-friendly IDE or integrated

development environment developed to allow for a

simplified version of the C++ programming

language. Users who minimize programming

backgrounds can write and upload programs through

this IDE. Arduino boards are available in a variety of

shapes and sizes with a variety of skills to meet the

requirements of your project. Many digital and analog

input start needles can be used to connect various

electronic devices such as sensors, actuators, and

more.

is detected, enhancing the system's user interface. It

helps to alert the user of potential obstacles or

hazards. Figure 4 shows the Arduino Buzzer.

Flame sensors are the heart of the system used to

recognize fire by capturing and capturing the

presence of flames. Flame sensors recognize

distinctive aspects of flame light, infrared radiation,

or ultraviolet rays, depending on the type of flame

radiation produced by the flame is classified into

unique regions of the frequency/wavelength die

5.1.7 SIM800L V2

The SIMCOM SIM800L V2.0 GSM/GPRS Module

is an Arduino-compatible quad-band GSM/GPRS

module. It facilitates the integration of the advantage

of these modules is that they operate at VCC and TTL

series levels using a 5-V voltage. Therefore, you can

directly interface it with an Arduino or any other basic

system at a 5V voltage. Many GPRS/GSM modules

are available on the market, necessitating the use of a

5-V regulator and level converter circuit. However,

the SIM800L V.2 GSM/GPRS module features a

built-in control circuit and a TTL level converter.

Below is a sample project based on SIM800L V.2 that

demonstrates how to control relays using SMS

controllers. It allows you to easily toggle and turn off

various devices at home, such as lamps, fans, and

more.

The Arduino Integrated Development Environment

(IDE) is a software application used for writing,

compiling, and uploading code to Arduino

microcontroller boards. It provides an intuitive and

user-friendly platform for programming Arduino

projects, even for those with minimal coding

experience. Figure 8 shows the Arduino IDE

Software Interface.

6 FUTURE SCOPE

There may be other sensors that need to be integrated

into the system and may be connected to temperature

and pressure sensors. Therefore, IoT gas recognition

systems can be integrated into Smart Home

Automation Systems over the next few years. This

integration ensures that cutoffs and emergency

protocols are triggered in the event of a gas leak,

improving security to reduce human intervention.
