3. ABSTRACT The presence of hazardous LPG gas leakage in a domestic, work place, also stored gases container which exhibits ideal characteristic in use. For that sake,an alarm unit is used to vibrate an alarm which is buzzer. Buzzer gives an audible sign of the presence of LPG volume. The sensors are widely used to detect essence of propane, iso -butane, LPG and even smoke. If the LPG sensor senses gas leak from work place or home, sensor output goes to NodeMCU used in the project. Through the NodeMCU Turns on the B uzzer And It even turns on the GSM modem after that, it continues to send SMS messages to mobile number specifically mentioned in the program of the source code for alerting danger to the people and the servo motor closes the regulator valve

4. ABOUT DOMAIN The Internet of Things ( IoT ) is a technology where the things are embedded which is connected over the internet like software and the internet enabled sensors which is collecting the data in the cloud. The data can be retrieved when it is required

5. EXISTING SYSTEM In the existing method, different gas sensing technology is used. The LPG gas leakage is detected by the semiconductor sensor. Nowadays LPG accidents occur very common. The main reason of these accidents is due to the leakage of LPG. This leakage of LPG starts when we forget to close the main regulator valve. This is the basis of these kinds of accidents. Already there are some sorts of remedial measures such as when the leakage is detected, alert message

6. PROPOSED SYSTEM This process starts when the gas leakage occurs, the gas sensor senses it and gives an output to the micro controller. The micro controller used here is NodeMCU which converts this output into digital format and sends it to the Application, and to the motor driver. The alarm to alert the neighbours in case of absence of the user at home where as the Application displays the warning message. For the controlling purpose, Servo motor driven by motor drivers are used which closes the main power supply and the cylinders valve to stop the flow of current and LPG gas.
