A Critical Review on LPG Gas Leakage Detection and Monitoring System
Kajian Kritikal terhadap Sistem Pengesanan dan Pemantauan Kebocoran Gas LPG
This paper reviews past, existing, and future gas leakage detection and monitoring systems. Over the past few years, there has been an increase in interest in technologies, systems, and procedures to detect and monitor gas leakage in reducing the number of fire accidents and injuries related to subjects. The gas leakage detection activity with a combination of GSM and IoT-based systems has become more important as this medium is more efficient, practical, and cheaper in monitoring capabilities. In January 2018, Fire and Rescue Department Malaysia reported there are 48 cases of accidents that occurred related to gas (Fire and Rescue Department Malaysia, 2018). Thus, this statistic indicates the need for reliable and efficient gas leakage detection and monitoring with a safety system that could alert or warn the user/people at surrounding before any mishaps happen. Several approaches and methods have been developed to reduce the incident related to the subject, which uses the following measures: (1) monitoring-based measures; (2) detection-based measures; (3) tool or mechanical system-based measures. This paper briefly reviews the literature on gas leakage detection, monitoring, and safety systems. The findings from this review are discussed in the light of directions for future studies and the development of gas leakage countermeasures.
