Nowadays, the accidents due to gas leakage are claiming the most number of lives. Almost, everyday, we come across incidents where the negligence of an individual living in an apartment, or any defect in the commercial gas pipelines have turned fatal to the people around. The negligence may result in fire or gas leakage accidents. The statistical growth of these types of incidents gave us an alarm that it’s time to renew our existing alert systems and propose a novel one. Our proposed system consists of a number of nodes which can be placed in each flat of the apartment and the master node, located in the control center of the apartment. In case of a fire or gas leakage, the message is directly transmitted to the master node. Thereby, necessary action is taken automatically. In addition, it provides auto shut-off system for the gas leakage, thus conserving the gas and saving numerous lives.
