Gas leakage is a serious problem in homes and industries. Accidents resulting from gas leakage can cause damage to properties worth millions of dollars and also loss of life. This paper presents the design and construction of a carbon monoxide and liquefied petroleum gas leakage detection and alert system. This system uses two gas sensors to detect leakage of the individual gases and sends the information to the microcontroller. The microcontroller was programmed using Embedded C programming language to collect input data from the different sensors, process them according to set instructions and give necessary outputs to activate an alarm to warn the individuals around of the gas leakage. A short message is also sent through a global system for mobile communications (GSM) module to a predefined number indicating the location for necessary actions to be taken. The system successfully detected carbon monoxide and liquefied petroleum gasses respectively and suitable for use in areas were these dangerous gases are in use. It will also reduce loss of lives resulting generators fumes in residential houses.
