4. INTRODUCTION
 LPG leakage detection system which help in our security
and make our home and kitchen safe from the LPG leakage
system.
 this system can detect easily the gas in the surrounding.
 you now not need to worry about the LPG leakage.
 there is some buzzer or speaker for alert the people.
 LPG leakage system show value into the analog format.

8. WORKING / PROCEDURE
We have used an LPG gas sensor module to detect LPG Gas.
When LPG gas leakage occurs, it gives a HIGH pulse on its
D0 pin and Arduino always reads its DO pin. When
the Arduino board gets a HIGH pulse from a gas sensor then
it displays a message LCD display and activates buzzer to
generate beep sound.

10. APPLICATION
 security system in applications like homes, hotels ,Industries,
vehicle (LPG as fuel).
 because of its low power consumption this system can be used
in other application like, smoke detection and various toxic
gases by doing some modifications.

12. CONCLUSION
 Gas leakage may leads to severe accidents which results in
material losses and human injuries.
 Gas leakage occurs mainly due to poor maintenance of
equipment and inadequate awareness of the people.
 Hence LPG leakage detection will be helpful to prevent
accidents and to save human lives.
 This system triggers buzzer and displays the severity of the
leakage to alert people when LPG leakage is detected.
 This system is very simple yet reliable.
