IoT Based LPG Leakage Detection – Result Based

Computer Engineering

Liquefied Petroleum Gas (LPG) is being used for heating in a wide range of domestic, industry and automobile applications. There has been a serious safety concern relating to LPG leakage in the environment. Exposure to LPG would cause explosion and affect the well-being of the people in the nearby area if it is not carefully monitored. An Electronic Nose (e-nose) system is used to monitor the gas and trigger an alarm as well as control the leakage within the environment. The environment is monitored by using wireless e-nose known as node, which is installed inside the environment. The node consists of two LPG gas sensors as well as a temperature sensor. The acquired data is sent wirelessly to the base node through Wi-Fi communication protocol. The acquired data is analyzed by the base node to automatically determine the gas concentration in the environment and leakages. The system used an alarm and an indication lamp to alert the staff within the plant if gas leakage is detected. It will also automatically activate the water sprinkler system and exhaust fan which will reduce the gas concentration. Initial result shows that the system can detect the leakage when the gas concentration exceeds the pre-set value. This indicates that the system could be used to monitor the gas leakage in the environment.
