Abstract - The growing popularity of LPG as an economical
detection include low cost, ease of customization, and a strong DIY (Do-It-Yourself) community that can help individuals design and implement their own gas detection systems. It is a practical and accessible solution for ensuring the safety of homes, commercial kitchens, and other places where LPG is used.
and environmentally friendly fuel means that inexpensive and dependable gas leak detection devices are needed to improve home and workplace safety. This work describes the development and application of a low-cost LPG gas leak detection system that balances affordability, accuracy, and sensitivity. A microprocessor is coupled with a gas sensor that has a high sensitivity to LPG in the suggested detector to process data in real time. When the system detects LPG concentrations over safe thresholds, it is intended to sound an audio and visual alarm to alert occupants in a timely manner. A greater variety of consumers can use the detector since easily available materials and components are used to reduce expenses. The efficiency of the detector in quickly detecting gas leaks is demonstrated by the results of studies that simulate different leakage scenarios. Furthermore, the device's low cost makes it appropriate for broad deployment, enhancing safety standards in settings where LPG is often used.
2. LITERATURE REVIEW In past years many LPG gas detector have been proposed to detect leakage of LPG efficiently. Some use different sensors like MQ in place of MQ-2 gas sensor. There is a user who has designed the appliance that turns off the gas line by sending them a text message. Some even used buzzer and leakage detector system. This paper discusses about the cost and efficient as compare to market LPG gas detector and end of the time this project is user friendly and very less price. These detectors are essential for maintaining safety in environments where LPG (liquefied petroleum gas) is often utilized, such as homes and businesses. Traditional gas detection systems, such as electrochemical and catalytic combustion sensors, were the main focus of early research. But more recently, materials including metal oxides, polymers, and nanostructures have been used to create innovative sensing technologies. These developments have maintained or even improved detection sensitivity and accuracy while drastically lowering production costs. Owing to their high sensitivity to LPG and low cost, metal oxidebased sensors have been the subject of numerous investigations. Usually, these sensors detect changes in electrical conductivity when they come into contact with LPG gas. Additionally, the creation of nanostructured metal oxide materials has been made possible by advances in nanotechnology.

1. INTRODUCTION Liquefied Petroleum Gas (LPG) is widely used for cooking and heating in many households and industries. However, the improper handling or leakage of LPG can lead to hazardous situations, including fires and explosions. To ensure safety and prevent such incidents, the development of low-cost and efficient gas leakage detection systems has become essential. One cost-effective and popular solution is the use of an Arduino-based gas leakage detector in combination with the MQ-2 gas sensor and this is a widely available and affordable component known for its sensitivity to a variety of gases, including LPG, methane, propane, and even smoke. When LPG gas is detected in the environment, the sensor's resistance changes, and this change is monitored and processed by an Arduino microcontroller. The Arduino, a versatile open-source microcontroller platform, is programmed to interpret the sensor's data and trigger appropriate responses in case of a gas leakage. This can include sounding an alarm, sending alerts through various communication channels, and even shutting off the gas supply to prevent further leakage. The system offers real-time monitoring, early detection, and a timely warning mechanism to protect lives and property. The advantages of using Arduino and the MQ-2 sensor for LPG gas leakage
