Abstract

In human’s daily life, environment gives the most significant issues which is related to human health. Therefore, environment and workplace air quality issues are seriously discussed to increase the awareness and responsibility regarding the threat on the environment towards public and workers health. Most of the dangerous gas such as carbon monoxide (CO), refrigerant gas and liquefied petroleum gas (LPG) is the compounds that are produced by incomplete combustion. In kitchen restaurant, the LPG leakage and the presence of combustible gas which are produced from cleaning and cooking process. These will cause explosion or fire and may harm the restaurant worker or even customer. The traditional method use for most people to detect cooking gas leakage by using soap water are not effective if the leakage occur when the restaurant are closed where no one there. A Gas Alert System is the best solution in this case as it will send an alert to the owner of the restaurant if it detect the presence of abnormal gas condition in the restaurant. This system also provide a precaution step by activating kitchen exhaust fan if the concentration of gas in warning stage and activating alarm at the dangerous level. A Gas Alert system will able to detect LPG leakage and the presence of combustible gas by using MQ-2 sensor. By using Global System for Mobile technology, an alert can be sent to the phone. This detecting provides efficient way to detect leakage and presence of combustible gas because human had limitation in order to detect the presence of those compounds. 4ii
