Automatic Liquefied Petroleum Gas Leakage Control System Using Proportional Integral Derivative (PID) Proportional

Abstract

Along with the development of technology and information, human needs toward kerosene stove in household sector change over to Liquefied Petroleum Gas (LPG) stove, which is cheaper and more effective.However, the use of LPG stove should consider precised procedures as the gas is easy to explode.One of some causes of gas explosion and burn is when people forget to turn off the stove while cooking and an existing gas leak.To address such human errors, a microcontroller-based tool needs to be developed to ably detect a gas leak and control the gas stove automatically.Equipped with a stepper motor, the tool can regulate the gas flow and the stove temperature.The tool also has a buzzer as a gas leak indicator and an LCD used to display the detection results from the MQ6 sensor.The MQ6 sensor is used as a gas detection and thermocouple sensor to identify the stove temperature that will be displayed in the seven segments.The gas stove's automatic control uses Proportional Integral Derivative (PID) method that can make precised valve opening angel of the stepper motor.The result of this research is expected to troubleshoot gas explosion and burn problems caused by the LPG stove.
