Liquid petroleum gas (LPG) is used for variant purposes at home such as central heating and cooking. LPG is primarily consisting of propane and butane which are highly flammable chemical compounds. Gas leakage can introduce risk of fire, which can occur inside homes, commercial premises or factories. Since the LPG does not have any odour, gas companies add an odorant such as Ethanethiol, Thiophene or Mercaptan so human can detect the leakage by the sense of smell. However, this is detection approach is not safe since sleeping person, children, low smell-sense people might not detect the leakage. Therefore, a more robust and reliable detection mechanism is required to increase safety at home. This project introduces a reliable, robust and instant-response solution for such a problem. Gas Leakage Detection System (GLDS) can detect leakage at homes, commercial premises or factories. Two highly important safety factors are considered in this system including: time and control. GLDS detects the leakage soon after it happened and sends users an immediate alarm on the incident. Moreover, by the application of the IOT (Internet of Things) people can control their home premises remotely. Consequently, in the case of users being away from home, he/she can remotely interact with the system to control the safety at home by cutting off electricity or ventilating the house.
