Arduino Based LPG Leakage Detector with SMS Indication Using GSM Modem

The gas usage brings great problems in the domestic and industries. The inflammable gas such as Liquidized petroleum gas (LPG), which is commonly used in the houses and factories. The leakage of the gas causes the property damage and affects catastrophically on people. So, by observance it in the concept of the project we have determined to develop an examining system which finds the leak of LPG gas and protects the property by taken correct precaution at correct time. The project consists of Alarm unit which is Buzzer gives an audible sign of the presence of LPG volume. The gas sensors are widely used to detect essence of harmful gases, LPG and even smoke. If the MQ-2 Sensor senses gas leak from industries or homes and it sends information to Arduino UNO. The Arduino UNO turns on the LCD, exhaust fan and buzzer. It turns on the GSM modem after that, it continues to send messages SMS to mobile number specifically mentioned in the program of the source code for alerting danger to the people. Hence, by using this system we can reduce gas leakage accidents and save the lives and properties.
