Abstract

LPG is an abbreviation from Liquefied Petroleum Gases that consist of substances such as propane and butane. It is highly flammable and can easily burn even at some distance from the source of leakage. LPG leakage is a major problem in residential area and may cause fatal inferno if the leakage is not prevented. One of the preventive measures to avoid the danger associated with gas leakage is to install a LPG leakage detector at vulnerable places. This project focuses on issues such as for the people who have a low sense of smell that may not be able to recognize upon this inherent safety mechanism and to alert people on the danger of gas leakage in their home and premises. The aim of this project is to design and build a system of a microcontroller-based prototype of domestic LPG leakage detection and to develop an automatic alert system by using GSM network with LPG supply cut-off valve with the aid of servo motor. The cutting-off of the LPG valve is to stop the gas from continuously flowing to surrounding. Besides, this system prototype is developed as a mechanism to provide community service in the form of educational kit for academic institutions, especially for schools and pre-university students to promote safety awareness and knowledge in engineering technology. When the system detects the LPG concentration in the air has reach certain levels of pre-determined settings, then it will immediately alerts users by sending signals to GSM network using SMS. As results, a servo motor is activated to safely cut-off the gas regulator knob or disable the LPG supply. This system is capable to minimize injuries or property loss associated by explosion due to gas leakage while using domestic cooking gas.
