IoT based Gas Monitoring System

Nowadays gas leakage has become a major issue. LPG gas is highly flammable and can cause severe damage to life and property. To prevent accidents from LPG gas leakage, a technology should be developed to detect gas leakage. Our project aims on reducing the accidents caused by gas leakage. This prototype describes the working of IoT based gas monitoring and gas leakage alert system. MQ135 and MQ2 are used to detect the LPG gas leakage. ARDUINO UNO serves as the primary controller to control the overall process. Load cells are used to measure the weight of gas present in the cylinder. One sensor (MQ2) will be placed near the gas valve and second sensor (MQ135) will be placed 4-5 feet away from gas burner. We have designed and application which will give details regarding temperature of the surrounding environment, amount of gas present in the gas cylinder and an alert message about the gas leakage. As an additional feature when the amount of gas in the cylinder will get below a certain threshold value, the application will automatically book another gas cylinder for the user.
