Abstract

Liquefied Petroleum Gas (LPG) has gained popularity in Indonesian households due to its efficiency and accessibility. However, LPG leaks often lead to fires and accidents. Research on an Internet of Things (IoT)-based gas leak detection system is being developed to provide early warnings and prevent fires, thereby enhancing household safety. This study focuses on developing a device to improve household safety. The hardware components include an MQ-2 sensor, NodeMCU for data processing and transmission, and an LCD for displaying detection results. Parameters tested include LED voltage, buzzer voltage, and output testing. The research demonstrates that the IoT-based gas leak detection prototype functions effectively. The MQ-2 sensor detects gas in the range of 52-161 ppm, with the NodeMCU ESP8266 showing a stable voltage of 2.85 volts. The LED and buzzer activate when gas intensity reaches 100 ppm, and a "Gas Alert!!!" notification is sent via the Blynk application. A green LED indicates a safe condition, while a red LED and active buzzer signal hazardous gas levels. This system effectively detects gas leaks and enhances household safety.
