Smart GAS Leak Detection

Abstract

Use of gases in houses, industries is a common practice, so there is a chance of gas leakage which is a serious problem now-a-days. This problem might be in the tube that is used for connection or not turning off the cylinders when they are not in use. As LPG is highly inflammable, it can cause damage to surroundings even far from the source of leak. This damage includes both material and human loss. Our Project deals with detecting such leakages and preventing accidents. Project is based on IoT (Internet of Things). Using a MQ-6 gas sensor to detect gas leakage to which a microcontroller named Node MCU ESP8266 is connected which process the input from the sensor. When sensor detects gas leakage we are notifying user about the gas leakage using Blynk app and also alert nearby people using buzzer which gives sound and an LED which gives light, so that necessary measures would be taken to avoid accidents and to prevent damage.
