IoT based Automatic Electricity Cut off using LPG Gas Leakage Detection System

Now a days, along with the advancement in internet, automation has been gaining significance in cutting off electricity in the residential areas. This paper discuss about the system disconnecting electricity supply if there is possibility of LPG gas leakage in the houses to avoid fire accidents. The Liquefied Petroleum Gas comprises of propane and butane. Its property of versatility makes user to utilize it in various applications like domestic fuel and industrial fuel etc. Several fire accidents are taking place due to human careless, forgetting to switch off regulators when not in use. During the operation of electrical appliances and functioning of fan, light etc. if the leakage of LPG gas occur, there is possibility for fire accidents. So, this paper presents IoT based system for disconnecting electricity if LPG gas leakage is sensed. If the LPG gas leakage is detected, the GSM modem, LCD and exhaust fan are activated. The user will be intimated about gas leakage and electricity is cut off through SMS using GSM modem. To avoid fire accidents, this proposed system using IoT platform is refined and exhibited here.
