Smart Home Gas Management System

Abstract

Within the constantly evolving domain of smart home design, the persistent risks posed by gas leaks and fires present significant challenges, especially when crafting a kitchen model that is thorough and secure. Incidents stemming from gas leaks and fires can result in substantial damage to property, underlining the pressing need for sophisticated detection and prevention methods. The potential for flammable gas leaks to ignite fires and cause explosions stresses the necessity of integrating sensor-based initiatives for real-time monitoring. In response to these challenges, a proposed smart management system integrates gas leakage and fire detection through a micro- controller. By utilizing sensors and actuators, this system notifies users of gas detection through SMS alerts. Addressing vital concerns such as gas leak detection, alert systems via SMS and mobile notifications, user interface enhancements, booking functionalities, auditory alarms, and load cells for monitoring consumption, this all-inclusive system seeks to avert property and human losses in addition to warning users of gas leaks and home fires.

Introduction

The rapid advancement of smart home technology has significantly transformed how we manage living spaces, with safety and security—especially in kitchens—being critical concerns. Kitchens are prone to hazards like gas leaks and fires, which conventional detection systems often fail to address promptly. This study proposes a sophisticated smart kitchen management system using advanced sensors (gas, flame, load cells) integrated with microcontrollers like the ESP32 to enable real-time monitoring, early detection, and proactive intervention.

The system employs multimodal sensors and actuators, a user-friendly mobile app interface, and alert mechanisms (SMS, smartphone notifications, audible alarms) to enhance safety and provide peace of mind. It improves on past IoT-based solutions by integrating real-time data monitoring, automatic gas consumption tracking, and emergency protocols like gas valve shutoff and fire alarms.

The literature review highlights several existing IoT gas and fire detection systems, noting their features and limitations—such as delayed alerts, lack of valve control, or insufficient integration with communication technologies. The proposed system addresses these gaps by combining state-of-the-art sensors, remote monitoring, and proactive safety measures.

Implementation involves a hardware-software integration: hardware includes sensors, ESP32 microcontroller, GSM module, and load cells; software includes a mobile app for remote control and notifications. The system detects hazardous events, triggers alarms, sends alerts, and guides users through emergency responses, ensuring comprehensive kitchen safety.

The design emphasizes adaptability, real-time responsiveness, and user convenience, representing a significant step forward in smart kitchen safety within the broader smart home ecosystem.

Conclusion

The implementation of a smart home gas management sys- tem yielded promising results, significantly enhancing safety and security in the kitchen environment. Real-time monitoring capabilities enabled the timely detection of gas leaks and fire incidents, leading to prompt responses and mitigating potential hazards effectively. User feedback highlighted the convenience and ease of use provided by the intuitive user interface, allowing for seamless interaction with the system. Integra- tion with mobile notifications and booking functionalities further improved user experience, empowering homeowners to actively manage their kitchen environment. Overall, the smart gas management system demonstrated its effectiveness in enhancing safety, optimizing resource usage, and providing peace of mind to users in smart home environments. Ongoing discussions centered on fine-tuning system parameters, expanding integration with other smart home devices, and leveraging data analytics for continuous improvement. Fig 4 displays the hardware components integral to the smart home gas management system, encompassing the GSM module, temperature sensor, flame sensor, humidity sensor, MQ6 gas sensor, buzzer, load cell, relay bulb, and ESP32 microcontroller. The temperature sensor serves to monitor temperature fluctuations, while the flame sensor identifies the presence of flames, triggering a beep from the buzzer upon detection. Similarly, the MQ6 gas sensor is responsible for detecting gas leaks, prompting an alert from the buzzer. The load cell plays a crucial role in measuring the container’s weight, facilitating gas consumption monitoring. Upon gas leak detection, the relay bulb blinks as an additional visual indicator. The ESP32 acts as the central hub, orchestrating the interconnected functionalities of all components. Additionally, the GSM module, equipped with a SIM card, enables commu- nication by sending SMS notifications to users in the event of fire or gas leak detection. Within the relay bulb, upon gas leak indication, automatic electricity shutoff occurs, extinguishing the bulb. Fig 5 illustrates the software components of a smart gas management system, designed to enhance user safety and efficiency. The system features a user authentication page, ensuring that access is securely managed. Key functionalities include a gas leak detection page that alerts users to potential leaks, alongside a flame alert system for immediate notification in the event of fire. The software also integrates environ- mental monitoring, displaying temperature, humidity, and gas levels in real-time. For user convenience, there is a booking
