Abstract

LPG gas has become a primary energy source in society since the conversion program from kerosene in 2005. However, its use is not without risks, as leaks can lead to fires or explosions. According to data, 64% of fire incidents caused by gas leaks occur due to delayed handling, while surveys reveal that 78% of households using LPG are concerned about the risks but do not have adequate detection systems. This research aims to develop an IoT-based LPG gas leak detection system that provides early warnings and automatically shuts off the gas flow. The system uses a NodeMCU ESP32 as the main controller, an MQ-6 sensor to detect gas concentration, and a TD8120MG servo motor to control the gas regulator. It is equipped with a buzzer, LED indicators, an LCD to display gas concentration, and real-time notifications via the Telegram application. Testing results show that the system can accurately detect gas leaks at a threshold of 200.0 PPM. When a leak is detected, the system automatically activates a buzzer as an alarm, turns on the red LED as a danger indicator, and sends real-time notifications via Telegram with an average delay of 1–2 seconds. The TD8120MG servo motor successfully controls the gas regulator automatically when a leak is detected, moving from the closed position (180°) to the open position (0°). The servo motor also proves effective in automatically shutting off the gas flow to prevent potential hazards. Additionally, the auto-reconnect feature ensures stable WiFi connectivity, allowing notifications to be sent consistently without interruption. This system provides an effective and user-friendly safety solution, enabling users to monitor gas cylinder conditions remotely while offering an additional layer of protection. The applied IoT technology makes the system more responsive in addressing the risks of LPG gas leaks in households, ensuring quick detection and action in emergency situations.
