In India almost all the peoples are using Liquefied Petroleum Gas (LPG) as a fuel for cooking. But in this field the steps taken for safety purpose is very less. LPG is flammable gas, it has the potential to cause fire accidents heavily. In order to avoid fire accident, many researchers are applied their effort to design new prototype model. IoT based gas leakage detection and monitor system uses different sensors and gas knob to avoid the fire accident in the kitchen. It will acquire input from the sensor and control the gas knob automatically either from High ignition to Medium or from Medium to Low. Gas leakage and presents of moisture will enable the DC motor to rotate the gas stove knob automatically to stop the gas flow in the gas stove. If gas leakage is detected then it will be intimated to the end user by using pushing box option in the cloud environment. The proposed model also enables the user to analysis the usage of gas throughout the year. © 2018 IAEME Publication.
