So many systems are available in the market which are designed with different types of controller, but they are expensive as well as they are not much effective and efficient. By considering these issues, we have designed a system which automatically detects and prevents gas leak with instant SMS alerting system. This system gives alert for the blast or any hazardous intimation during gas leakage condition to user mobile phone through SMS. And automatic prevention is done by using exhaust fans which are used as in-let and out-let. And a buzzer is used to alert the surrounding people.Our system consists of gas sensor to detect any gas leakage as soon as it is encountered. The gas sensor which senses the harmful gas sends a signal to the arduino so that microcontroller can process it further. Once the arduino receives signal from the sensors, it processes the input and then sends a signal to the GSM modem to send an SMS to the intended authorities so that they may take appropriate action. Here the gas is prevented by the exhaust fans and alert the people by buzzer sound.
