REAL-TIME HAZARDOUS GAS DETECTION AND WARNING SYSTEM VIA EMBEDDED TECHNOLOGY

Abstract

Numerous incidents, including explosions and fires, have occurred due to LPG gas leakage. Such incidents can have perilous consequences if the leakage is not identified promptly. The Arduino and IoT-based LPG leakage detection system is a project designed to identify gas leaks in the environment and transmit data to an IoT module. The Internet of Things (IoT) refers to the interconnection of physical objects that communicate through sensors, electronics, software, and connectivity. These systems operate autonomously, and the same applies to IoT- based gas detection systems, which do not necessitate human oversight. Safety is paramount in contemporary society, necessitating the implementation of effective safety systems in educational and occupational environments. This work alters the current safety model implemented in industries, and this system can also be utilized in residential and commercial settings. The primary aim of the project is to design a microcontroller-based system for detecting and alerting toxic gases. The hazardous gases, such as LPG and propane, were detected and displayed continuously on the LCD screen. If these gases surpass the normal threshold, an alarm is triggered immediately, and an alert message (SMS) is dispatched to the authorized individual via GSM. The automated detection and alerting system surpasses the manual method by providing rapid response times and precise identification of emergencies, thereby facilitating the expedited resolution of critical situations.
