INTRODUCTION Liquefied petroleum gas (LPG) accidents are a significant societal issue, affecting the use of highly pressurized and cold LPG gas, primarily used for cooking and as fuel in generators and water heaters [1]. LPG, a flammable mixture of propane and butane, poses significant safety risks, necessitating continuous monitoring and Internet of Things (IoT) technology to prevent gas leakage and ensure human safety [2]. Home security is a major concern due to Liquid petroleum gas leaks, posing a threat to commercial and residential use. Technology is crucial for preventing explosions and fires, and using LPG gas detectors can help [3]. The IoT's MQ-2 sensor, when integrated with an automatic gas leak detection system with a self- regulating valve, ensures safety and minimizes gas wastage [4]. This work proposes distributed field-oriented IoT gas sensing robots for detecting dangerous flammable gases like ammonia, sulphur dioxide, nitrogen dioxide, and carbon dioxide in the environment [5]. The IoT is a rapidly evolving technology that connects social environments through interconnected sensors, enabling data communication via internet connectivity [6]. IoT connects physical devices with sensors, enabling data exchange and expanding internet reach. It
