 Introduction

Flame is the visible, gaseous part of a fire. It is caused by a highly

exothermic reaction taking place in a thin zone. Flame, rapidly reacting body of

gas, commonly a mixture of air and a combustible gas that gives off heat and

light, and is self-propagating. It is the glowing gaseous part of a fire.

Fire is the rapid oxidation of a material in the exothermic chemical process

of combustion, releasing heat, light, and various reaction products. Fire occurs

whenever combustible fuel in the presence of oxygen at an extremely high

temperature becomes gas. Fire in its most common form can result in

conflagration, which has the potential to cause physical damage through burning.

It is the reason why nowadays we need a fire alarm system in our house.

A fire alarm is a standalone device or a complete network of devices,

installed in a building or an area, which gives audible and/or visible warning of an

outbreak of fire in that building or area. Fire alarm systems are mandatory in

buildings, industrial installations, markets, offices, living spaces, public areas and

some kinds of transports. Fire alarms are generally audible and/or visible,

mechanical or electrical signals or intelligence, indicating a fire incident that

requires emergency actions such as fire-fighting, emergency services and

evacuation from a building or an affected area. There are three stages of Fire

Alarm System, the detection, signal initiation and notification.

Page | 1
 There are many kinds of fire alarm system like Fire Alarm System with

SMS notification that detects the fire through flame sensor and gives signal

initiation

through a sound and light and notification through sending an SMS to the owner.

It sends an SMS to a set mobile numbers when fire occurs. It is very useful in

remote locations where human interaction is limited. It also helps to monitor

locations and alert during fire that occurs at night time. Furthermore, it gives

warning immediately to multiple mobile numbers and hence remedy can be taken

quickly and helps to prevent major damages and losses created by a fire

accident.

 Design Details

1. Components

Table 1. List of Components

ARDUINO UNO – It is used to execute the commands

that sensors, module, led, and buzzers need to run.

POWER SUPPLY – It is a 5 Volts 2 Amperes power

supply that will be connected to Arduino after coding to
have supply.

FLAME SENSOR MODULE – It is used to detect the fire/

flame source or other light sources of the wavelength in

Page | 2
the range of 760 nanometer to 1100 nanometer.

SIM 900A GSM/GPRS MODULE – It is the device that is

connected to the flame sensor module that sends SMS to
the set mobile number when the flame sensor detects
fire.

BUZZER – It is connected to the flame sensor so that

when it detects fire it will give a sound that alarms people
around the area.

LED (Red) – It is also connected to the flame sensor so

that when it detects fire it will give a red light that alarms
people around the area.

CONNECTING WIRES – It is used to connect the

component.

Universal PCB – It is where the components are

soldered to connect them to the power supply.

Resistor (470 ) – it is connected in series to the LED.

7. System Operation

The flame sensor module is sensitive to a flame and its radiation. It can
detect ordinary light source in the range of a wavelength from 760 nm to 1100
nm. Using this flame sensor, you can detect infrared light up to a distance of 1 m
within its detection angle. At which a phototransistor is the one who senses light
levels. Under normal conditions, the output from the flame sensor is high. When
the sensor detects any fire, its output becomes low. After the Arduino Uno
checks the logic state of the flame sensor, it therefore triggers the buzzer and
LED, also the GSM module. The GSM module sends an sms to a registered

Page | 10
 receiver alerting that the house is on fire. After the flame is out of range of the
sensor, the buzzer and LED automatically turns off.

2. Flame Sensor Module

KY-026 Flame Sensor Module for Arduino detects infrared light emitted by

fire. The module has both digital and analog outputs and a potentiometer to

adjust the sensitivity. Commonly used in fire detection systems.

The KY-026 consist of a 5mm infra-red receiver LED, a LM393 dual

differential comparator a 3296W trimmer potentiometer, six resistors and two

indicator LEDs. The board features an analog and a digital output.

Connect the board's analog output (A0) to pin A0 on the Arduino and the

digital output (D0) to pin 3. Connect the power line (+) and ground (G) to  5V and

GND respectively.

3. Buzzer

A buzzer is a small yet efficient component to add sound features to our

project/system. It is very small and compact 2-pin structure hence can be easily

used on breadboard, Perf Board and even on PCBs which makes this a widely used

component in most electronic applications.

The buzzer can be used by simply powering it using a DC power supply

ranging from 4V to 9V. A simple 9V battery can also be used, but it is recommended

to use a regulated +5V or +6V DC supply. The buzzer is normally associated with a

switching circuit to turn ON or turn OFF the buzzer at required time and require

interval.

Specifications:
Rated Voltage: 12V DC
Operating Voltage: 8V DC to 16V DC
Rated Current at Rated Voltage: 30mA
Sound Output at 10cm, at rated voltage: ≥85dB
Resonant Frequency at rated voltage: 2,300 ±300Hz
Operating Temperature: -20°C to +70°C
