<![CDATA[The cause of the leak was triggered by a hose that was no longer suitable for use so that it could cause gas leaks which could have an impact on the explosion of LPG gas cylinders. By making a security system for LPG gas with a microcontroller based MQ-6 sensor using an alarm and SMS, it can help users to find out the occurrence of a leak in LPG gas. As this tool works when there is a gas leak, the MQ-6 detects that there is a leak in the LPG gas hose, so the alarm will sound. When it is on, the sound will send a command to Arduino to close the LPG gas valve. Then the buzzer alarm will send commands to the user via SMS to notify you that "gas leak has occurred". The implementation of this device is useful so that users can quickly find out leaks in the gas so that they can take steps to avoid an explosion on the gas stove. The conclusion is that this LPG gas leak detector control system can help the community, especially housewives, and can also help to avoid fires due to LPG gas leaks.]]>
