Modern safety infrastructure must include gas leak detection systems and fire alarm sensors since they quickly identify and warn inhabitants of possible threats, protecting both lives and property. When a fire or smoke is detected in a monitored area, fire alarm sensors use a variety of technologies, such as heat, flame, and smoke detection. These sensors are frequently linked to alarm systems, which send out visual and audio signals to alert authorities and residents of the potential threat. On the other hand, gas leak detection systems are made to identify dangerous gases like propane, methane, or carbon monoxide when they are present in a closed area. These systems use sensors that are sensitive to particular gases; to detect even tiny levels of gas, they frequently make use of technologies like infrared spectroscopy or electrochemical sensors. As soon as it was discovered, gas Leakage systems set off safety precautions, including ventilation or gas shutoff mechanisms, to reduce the risk of exposure or ignition. They also activate alarms to warn occupants. Combining gas leak detection with fire alarm sensors improves overall safety by detecting any risks early and enabling prompt evacuation or intervention to reduce damage and avoid accidents. Furthermore, more thorough and effective detection capabilities are made possible by developments in sensor technology, such as the creation of smart sensors and networked monitoring systems, which promote quick response times and well-coordinated emergency management. In order to protect residential and commercial environments from the risks posed by fire and gas leaks, as well as to ensure tenant well-being and property preservation, it is imperative that these systems be deployed. Introduction: LPG is essentially a highly combustible mixture of butane and propane. If there are any power fluctuations, it reacts right away and could explode. The degree of protection against risk and loss is known as safety. High safety features and warnings are required with the aid of technology to guarantee that there is adequate time to avert possible threats. The suggested system finds leaks of LPG gas. The MQ-5 sensor detects gas leaks, and the Arduino signals the relay to shut off the main power supply.
