Project Objectives
 To study the working principle of gas and smoke
detector system
 To design and construct of the gas and smoke
detector system and control system using Arduino
with Bluetooth module
 To implement gas and smoke design in the project
 At the very first time of smoke creation so that
avoided the unwanted accident

Literature Review
 A smoke system is number of devices working
together to detect and warm people through visual
and audio appliances when smoke and carbon
monoxide.
 A smoke detector is a device that senses smoke,gas.

Features Of MQ-5 Smoke Sensor
The MQ-5 smoke sensor is sensitive to smoke and to
the following flammable gases:
 High sensitivity LPG
 Natural gas
 Town gas
 Butane
 Small Sensitivity Alcohol , Smoke

Connect MQ-5 Sensor
 The MQ-5 has 4 pins: Vcc,GND,A0,D0
 Right Now I Will Only Deal With 3 pins.
 Here is how you should connect the MQ-5 to your
Arduino
 Vcc to Arduino 5v
 GND to Arduino GND pin
 A0 to Arduino analog pin A5

What is Arduino ?
 Arduino is an open source electronics platform based
on easy to use hardware and software.
 ATmega328 microcontroller(8 bit)
 Input voltage 5v
 32k Flash Memory
 16 MHz Clock Speed
 Operation on +5v
 14 Digital I/O Pins(of which 6 are PWM)
 6 Analog pins

How does it work?
 When threshold voltage remain at minimum level
that time green light still on.
 When the smoke reaches a certain level, it will make
sound a buzzer and a red LED will turn on.
 Bluetooth system also included this process which
gives a signal by SMS on the smart phone.

Necessary Equipment
 MQ-5 gas sensor
 5V power supply
 Male to male to male to female jumper wires
 Arduino Uno
 Arduino Bluetooth Module
 Breadboard
 LED
 Buzzer
 220 ohm resistor

Circuit Diagram of smoke detector

Application
 They are used in gas leakage detecting equipment in
family and industry
 It is suitable for detecting of LPG , natural gas , town
gas
 Avoid the noise of alcohol and cooking fumes
cigarette smoke.

Advantages
 Detects Products of Combustion
 Sensitive Enough to detect level of gases
 Detects gases prior to reaching lethal levels
 Produced between the Occurrences of detectable
level and detectable heat levels

Disadvantages
 Can be Prone false alarms
 Must be mounted at a low level
 Can be Poisoned
 Not Suitable for areas where CO and CO2 and
Produced the functions within the area
 Cannot be considered as a universal replacement and
thermal detectors
 High Cost

Conclusion
 Smoke detector is One of the easiest and low
costly.
 Most of industries use it, Because it work fatly to
protect and most effective.
 In future the use of gas and smoke detection will
increases.
 In future we include Bluetooth Module
 At finaly we complete this project using 3 sensor
