2. ABSTRACT
This SMS-based LPG gas leakage detection system employs Internet of Things (IoT) technology to enhance
safety in domestic environments. Utilizing gas sensors, the system detects LPG leaks promptly, triggering
real-time alerts. A microcontroller processes sensor data and communicates with an IoT module, enabling
seamless connectivity. In the event of a gas leak, the system sends an SMS alert to registered users, providing
immediate notification. Users can remotely monitor and control the system through SMS commands,
ensuring proactive management. The system's swift intervention can prevent a minor leak from turning into
a catastrophic event. But its benefits extend beyond immediate safety. Imagine a scenario where you're
away on vacation. A leak occurs, but the SMS reaches your designated contact. They can rush to your aid,
mitigating the damage and ensuring your property's safety. The system empowers you to safeguard your
loved ones and valuables even when miles away. The integration of IoT facilitates continuous monitoring,
reducing response time and potential hazards. The system promotes energy efficiency by automating gas
supply control based on real-time leakage detection. Cost-effective and user-friendly, this solution enhances
home safety and aligns with the evolving landscape of smart technologies for a secure and efficient living
environment.

9. SYSTEM ANALYSIS
EXISTING SYSTEM
• In existing systems, lack of ability to effectively manage data makes it very difficult for an individual to control the
potential risks associated with the collected data. For example, once the data has been collected by a third party (e.g., a
big company), the lack of access to this data hinders an individual to understand or manage the risks related to the
collected data from him. Meanwhile, the lack of immutable recording for the usage of data increases the risks to abuse
them.
DISADVANTAGES
1. The existing system lacks continuous real-time monitoring, increasing the risk of delayed leak detection.
2. Manual checks are time-consuming and often result in false alarms or missed leaks.
3. Traditional systems are unable to provide alerts or notifications to users or authorities, causing potential safety hazards.
4. These drawbacks underscore the need for a more efficient and automated solution like the SMS-Based LPG Gas Leakage
Detection System using IoT.
