Abstract

Gas leakage is a major issue in houses and industries. LPG gas is widely used for cooking and other tasks. Gas leakage may result in fire and explosion. It may also affect human health. In this project, we designed a smart gas alarm system using ESP32 and MQ-6 gas sensor. We also used a temperature sensor to increase the accuracy of the system. The system continuously monitors the gas level. When the gas level increases, it alerts the user with an alarm and turns on an exhaust fan. It also sends an alert to the user via the internet. The system is cost-effective and helpful for safety.
