dc.description.abstract | The rampant fires caused by leaks of LPG (Liquefied Petroleum Gas) gas cylinders have recently become a frightening thing for the people who use the gas. Because of these various problems, a warning system is needed that can provide information on what is happening and overcome problems that occur in the house. The devices used to support this system include Arduino Uno as a microcontroller, MQ-2 gas sensor and flame sensor as a gas leak detection sensor and fire detector, buzzer as an alarm and LED as an indicator. The results of the tests show that the system has been able to work properly. control the gas regulator in the event of a gas leak or fire and provide information on gas concentration data, weight data from gas cylinders In making the device or gas leak detection device, it is also divided into two parts, namely first making the hardware (hardware), then software (software). The result of this tool detector is that the user can find out the LPG level due to a leaking LPG cylinder. The conclusion from this study is that users are safer because when there is a gas leak, the tool will detect LPG gas, LCD. If there is a spark from the gas leak, the flame sensor will detect the fire that has arisen, the light indicator is on, then the buzzer will sound. | en_US |
