Sensor Based: Gas Leakage Detector

Since there are a lot of cases about the gas leakage that happened in Malaysia and other countries, the author realized that having a portable detector could help others as gas leakage is fatal to human beings. Gas detection is an important element for protection plan for human life and property. This project is focused in the construction of a gas leakage detector that is user friendly and cost effective. It is a sensor based gas leakage detector and it made used of the catalytic type of sensor to detect the propane gas as primary gas of liquefied petroleum gas (LPG). The detector triggered an alarm when it detects from the surroundings at the amount of certain ppm (theoretically ranged from 200-10000ppm) where this was set during the experiment. Apart from that, a red light emitting diode (LED) turned ON when it detected gas leakage. The alarm gave warning to individual in order to do alternative measure and avoid any accident to happen. The prototype performed as required.
