Gas and smoke use every day of our life. A big number of accident happen today everyday life from the gas. A huge number of loss occur from gas and smoke in our everyday life. Gas speared so quickly that an accident happen so quickly. So basically we try to modify our project to make a gas or smoke detector that will response with the present of smoke and send warning sms.

4. Gas and smoke use every day of our life. A big number of accident happen today
everyday life from the gas. A huge number of loss occur from gas and smoke in
our everyday life. Gas speared so quickly that an accident happen so quickly and
gas line fault is the problem in our household works.If we identify the licakeg as
early as possible we can reduce the loss.
So basically we try to modify our project to make a gas or smoke detector that will
response with the present of smoke and send warning sms.

6. The Arduino Uno R3 is a microcontroller
board based on a removable, dual-inline-
package (DIP) ATmega328 AVR
microcontroller. It has 20 digital input/output
pins (of which 6 can be used as PWM
outputs and 6 can be used as analog inputs).
It has his own memory. The size of the
memory is 32K.

Arduino Uno:

7. TSB smoke sensor which detect the gas or smoke. The sensor had 4 pin
which one connect with 5v and GND.
Other 2 port for digital input/output pin and other one in analog
supported pin. In our project we don’t use digital i/o pin.

8. Sim Kit 900A:
Sim-kit, the main notifiyar in this project. It can make a call and send sms.
There is tower for and sim point for sim. Tower use for the sim which one is
use in the port, to get network. There is power supply 5v and 3.3v. We can
vary the voltage.

9. Buzzer:
Buzzer is an output device. A buzzer or beeper is an audio signaling device, which may
be mechanical, electromechanical, or piezoelectric (piezo for short). Typical uses of buzzers and
beepers include alarm devices, timers, and confirmation of user input such as a mouse click or
keystroke. To generate we use it. This one generates a continuous beep usually when supplied with
power. It works like alarm. Buzzer had 2 pin. One pin for positive and other for negative. To easily
identify positive and negative, the positive leg is bigger than the negative.

10. Breadboard:
A breadboard is a solder less device for temporary prototype with electronics
and test circuit designs. Most electronic components in electronic circuits can be
interconnected by inserting their leads or terminals into the holes and then
making connections through wires where appropriate.

Final:

16. Advantages:
 Automatic Emergency Services.
 Smart Smoke Detectors Work Best as Part of a Connected Home System.
 Quick response.
 Reduce loss.
16

17. Disadvantages:
 False alarms.
 Expensive.
 Network.

18. Conclusion:
When it comes to fire safety, it's best to have a smoke detector in every
bedroom and hallway, as well as on every floor in our home. With so
many smoke detectors, we can rest assured our home is protected from
the unthinkable.
