Automated Fire and Gas Detection: An Integrated Safety System using LabVIEW

Fire and gas leaks can be dangerous, causing harm to people and property. This paper presents a smart fire and gas detection system that improves safety using multiple sensors and automatic decision-making. The system includes four gas sensors and a five-channel flame sensor, both providing digital signals to detect risks. A voting method is used for gas detection to reduce false alarms. An LM35 temperature sensor also checks the surrounding temperature and alerts when it reaches dangerous levels. When a hazard is detected, the system turns on a buzzer and LED lights to warn people. An infrared sensor detects a human entry into hazardous areas and provides an alert. If a fire is detected, a sprinkler system automatically activates to control the flames. To handle false alarms, a push button is provided to stop the system, along with an LED indicator. All monitoring and control are done through a LabVIEW interface. This system provides a reliable and easy-to-use solution for fire and gas safety.
