question paper leakage detection and alert system

Abstract

This paper presents the design and construction of an SMS based Gas Leakage Alert System. Two gas sensors (MQ-6) were used to detect gas leakages in a particular location; their outputs are then interfaced with an 8051 microcontroller programmed in assembly language. A dedicated GSM phone with a line is connected through relays to the output of the microcontroller. The GSM phone is configured to send gas leakage alerts in the form of a short message service (SMS) message indicating the location to another GSM phone to enable prompt necessary action. The system enables monitoring of gas leakages in remote locations and thereby leads to a faster response time in the events of a leakage condition.

The aim of this project is to monitor for liquid petroleum gas (LPG) leakage to avoid fire accidents providing house safety feature where security has been an important issue. The system detects the leakage of the LPG using gas sensor and alerts the consumer about the gas leakage by sending SMS.

The proposed system uses the GSM to alert the person about the gas leakage via SMS.When the system detects the LPG concentration in the air exceeds the certain level then it immediately alert the consumer by sending SMS to specified mobile phone and alert the people at home by activating the alarm which includes the LED, Buzzer simultaneously and display the message on LCD display to take the necessary action and switch on the exhaust fan to decrease the gas concentration in the air.
