Arduino-Based Gas Leakage Monitoring and Treatment System

The use of gas in daily life is very important, especially in household life where it has become a major need. There are risks related to gas usage to the user and the community, such as gas leakage, which can be fatal and can cause fire to break out. Therefore, a system is needed to monitor and safely handle gas leakage. This paper discusses a gas leak monitoring and treatment system that uses gas sensor to detect gas concentration level, solenoid valve to open and close the gas valve, LCD to monitor and display gas concentration level, an exhaust fan to dispose gas from the room, buzzer as warning alarm, push-button switch to manually open gas valve after it has been closed, and Cayenne platform to send email notification to the user when gas leakage is detected. These devices are controlled by an Arduino Mega microcontroller board. From the system design and testing results, it can be concluded that the Arduino-based gas leakage monitoring and treatment system is working as expected in safely handling gas leakages. The success rate of gas sensor, solenoid valve, buzzer, push-button, and exhaust fan testing is 100%, and the success rate of email notification testing is 80%.
