Gas Detector Emergency Warning

Gas Detector Emergency Warning is a simple engineering project that provides the user a warning when there are gas leakage in the certain area such as kitchen in the house, storage gas room and etc. In this project we focus on the small area place to detect the gas leakage. The MQ5 Gas Detector has been selected to detect the Liquefied Petroleum Gas and from the gas detector it sends the small voltage between O - 5 V in analog form to the PIC 16F877 A that has been used in this project. The PIC will read the analog voltage value and display the result in Analog Digital Conversion value and Parts Per Million value as a reference for the user to take the precaution step before the catastrophe happen. The PIC also sends the digital signal to the buzzer, LED RED and LED GREEN as the warning and notify the user that has the gas leakage in that particular area.
