Abstract :
A liquefied petroleum Gas (LPG) leakage is an accident waiting to happen. Fire incidents resulting from LPG are quite
dangerous as it could lead to loss of lives and properties. Therefore, it is very important to measure liquid petroleum gas
concentration in an environment and to device a means to control it to prevent any possibility of fire incident. This work
aims at designing a system that detects LPG leakage and alert the user through alarm and status display and besides, the
system has the capability to turn close off the gas supply channel with an electrically controlled valve as a primary safety
measure. Reviews of previous studies in controlling the LPG leakage have shown that electrically controlled valve can
make significant job in preventing the gas to escape into environment as failure to do is quite dangerous. This present
study will extend the capability of the previous designs by incorporating a means of simultaneously alerting the user via an
electronic text message and ringing a buzzer as well. The system built was after the modification of the electrical circuits in
the previous designs and it was tested using a cigarette lighter. The lighter contains inflammable gas (methane gas). As the
lighter was opened up and the gas concentration near the device’s sensor was allowed to reach the threshold value of
45ppm (indicated on LCD), the system automatically activated itself and following events occurred: the buzzer rang, the
supply line valve was shut down and sixty seconds later, a gas leakage detection notification (SMS) was sent to the user via
the predefined phone number. The shutting of the supply valve stopped further gas flow to prevent occurrence of fire
incident. LPG users either at home or industry need to take preventive measure to detective potential gas leakage in their
environment. One way of achieving the objective of detecting and controlling gas leakage is to incorporate a device that
can automatically take action in the event of a leakage. The system designed and constructed in this project demonstrates
that it can automatically detect and stop gas leakage in vulnerable premises.
