ABSTRACT

Household safety is a major concern in our society. Fires caused by gas leakage is one of the factors that contributes to this problem because of safety measures in handling Liquefied Petroleum Gas (LPG) tanks that were most of the time neglected. To address this problem, the proponents developed an Automated LPG Detection System to aid homeowners in protecting their household from the possible dangers of LPG tank leakages. The system aims to serve as a safety measure by shutting off the tank’s gas line before reaching the critical level of leakage. The project saves gas leakage information according to the program embedded in the Arduino UNO. Using the MQ-2 gas sensor, the gas leakage will continuously be detected, once the leakage detected exceeds the normal level of 400 ppm, the alarm system will now start working. It consists of an LED module, GSM module and a buzzer that will be activated to inform the owner of the leakage. The device is operated by the microcontroller and the solid state relay activates the electric valve to turn the LPG’s knob off. The device is supplied by a 12V supply voltage.
