There has been a major rise in the fire incidents occurring over the past few years in the Pacific Island Countries (PICs) and especially property fires are a major concern. Often it is noticed that these usually lead to loss of homes, personal belongings and even lives of people. Objective of this paper to present a monitoring device that is able to detect the presence of a gas leak and take action before there is an actual fire. To optimize the decision of the system, a fuzzy logic based smart rules are developed to avoid false alarming. The prototype system is designed considering cost, simplicity and reliability. Further, the proposed system helps to reduce fire accident by triggering alarm well-in advance and therefore it can react as an early warning system.
