In today's world, safety is of utmost importance, both in educational institutions and workplaces. It is crucial to have effective safety systems in place, not only in industries but also in homes and businesses. One specific safety measure is the installation of gas leakage detectors in vulnerable areas. These detectors are devices that can identify the presence of gases, forming part of a safety system. When a leak occurs, the gas detector can sound an alarm, alerting individuals in the vicinity to take appropriate action. This is essential because certain gases can be harmful to living beings, such as humans and animals.

This paper introduces a novel approach to detect leaks of liquefied petroleum gas (LPG) using a microcontroller-based Node MCU. The goal is to detect and prevent LPG leaks, ensuring the safety of individuals and avoiding potential accidents. The proposed device continuously monitors the area using gas sensors. The data from these sensors is then transmitted to the Node MCU, which displays the results as a warning on an Android-based smartphone. Additionally, apart from LPG gas, the device can also detect leaked gases from air conditioners and refrigerators, which are equally harmful when released in a home environment. By utilizing this device, users can effectively prevent accidents caused by gas leaks, thereby ensuring their safety.
