The problem of gas leakage and fire is often encountered in our day-to-day life. LPG, Liquefied Petroleum Gas, is highly flammable gas used as fuel in heating appliances. Leakage of this gas raises the risk of building fire, suffocation or an explosion. Most of the fire-breakouts in industries are due to gas leaks. These cause dreadful damage to the equipment, human life leading to injuries, deaths, and environment. The mentioned problem can be solved with the development of reliable techniques to detect gas leakage. We proposed a system to detect gas leakage automatically with the help of gas sensor and Arduino microcontroller and alerts the person if there is gas leakage by buzzer alarm and also display like gas leakage detected on the LCD Display.

 

 

This is our proposed block diagram for automatic gas leakage detection. We are using Arduino Nano microcontroller as controller. We are providing power supply to the controller through 9V DC battery. As the controller, LCD and sensor requires 5V we are using 7805 voltage regulator which gives 5V output voltage and this regulated supply we are using as power supply. The gas sensor MQ-5 is used to detect gas leakage and it checks for gas leakage continuously and sends data to the controller. The controller analyzes the data received by the sensor and takes appropriate decisions. The buzzer is connected to the Arduino as output. If there is a gas leakage controller will turn on the buzzer to alert the person. 16x2 LCD display is connected to the Arduino in order to see the output. If there is gas leakage controller makes LCD to display gas leakage detected else gas leakage not detected.

The problem of gas leakage and fire is often encountered in our day-to-day life. LPG, Liquefied Petroleum Gas, is highly flammable gas used as fuel in heating appliances. Leakage of this gas raises the risk of building fire, suffocation or an explosion. In order to prevent the gas leakage we proposed a system for automatic gas detection. The gas leakage is detected with the help of gas sensor and Arduino microcontroller. The system will alerts the person by buzzer alarm and also display the same in the LCD display like gas leakage detected if there is a gas leak else it will display no gas leakage detected.
