Arm Based Gas Monitoring System

Abstract - In this paper our aim is to monitor for liquid petroleum gas LPG leakage to avoid fire accidents and hazardous condition providing house safety feature where security has been an important issue today. This system detects and monitor the leakage of LPG using gas sensor and alerts the persons about the gas leakage using the buzzer and by sending the SMS. This system continuously monitors the level of the LPG present in the cylinder When the system detects the LPG concentration in the air exceeds the certain level it immediately alerts the persons by activating an alarm and sending message to the specified mobile phones. The Proposed system uses the GSM to alert the person about gas leakage via SMS .Simultaneously to take the necessary action it automatically switches on the exhaust fan and sprinkler to decrease the gas concentration in the air.
