Abstract
The presence of hazardous LPG gas leakage in a domestic, work place, also, stored gases container gas which exhibits ideal characteristic is 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. The sensor has an advantage to combine a sensitivity response time. If the LPG sensor senses gas leak from work place or home, sensor output goes to active low (logic-0) condition. Arduino UNO is used in the project; low signals are overlooked by the Arduino and gas leakage is been noticed by the Arduino. The Arduino UNO turns on the LCD and buzzer. It even 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.
Highlights
The usage of the gas brings great problems in the domestic as well as working places. The inflammable gas such as Liquidized petroleum gas (LPG), which is excessively used in the house and at work places
The leakage of the gas causes destructible impact to the lives and as well as to the heritage of the people. By keeping 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 work places by taken correct precaution at correct time
The main objective of this project is that it is extremely accurate with a least cost, this project system is best to detect gas leakage and warn people around by buzzer beep sound and an SMS is been send to the responsible person for preparatory safety calculations
Summary
The usage of the gas brings great problems in the domestic as well as working places. By keeping 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 work places by taken correct precaution at correct time This system provides the information such as when a gas leakage is noticed, sensors of in the project are used to notice the gas leakage and immediately turns ON the buzzer for the danger indication. By taking references from the above paper we proposed a system which is used to detect leak of gas simultaneously at three different location and but it even alerts people by buzzer and by sending SMS by the GSM to the person whose number is written in the source code. The SMS received depends upon the leak of gas in the detection area of the sensor
