SGD: Smart Gas Leakage Detection System for Home Safety

Nowadays, gas leak detection equipment in the workplace, schools, and homes plays a vital role in protecting public safety. Liquified Petroleum Gas (LPG) leaks are one of the most serious issues in the kitchen because they raise the possibility of an explosion. LPG is the main cooking fuel in Libya. Multiple incidences of household fires, injuries, and deaths have been recorded in Libya as a result of LPG leakage and explosions, as the country’s citizens do not have gas leak-detecting systems. This paper aims to present the design and implementation of a smart gas leak detection system based on Arduino. In this system, an Arduino Uno microcontroller with an MQ6 sensor was used to detect gas leakage, an air fan motor to reduce gas concentration by ventilating the air, and GSM as a wireless communication method to notify users via SMS. The proposed system identifies three gas leakage risk levels, each Including its unique scenario. Level one is low-risk, the user is notified Unhealthy status of the dwelling due to gas leakage. level two is medium-risk, the user’s friends are informed about the unsafety status due to gas leakage in the user’s home. Level three is high-risk; the nearest firefighting organizations are informed of the hazard status. The experimental findings demonstrate that the system is capable of efficiently detecting gas and protecting individuals from a range of undesired situations, as well as being useful in reducing resource and human life losses.
