Development of smart homes is the recent trend all over the world. For cooking purpose LPG is predominantly used while using this leakage may lead to disaster. This paper focuses the regular issue occur in routine life that gas level detection in domestic LPG cylinder by using IOT concept and helps to book another cylinder at the time of low gas level. To detect the gas in LPG, MQ2 sensor is used, and any gas leakage arises the sensor detects by making an alert with buzzer. The sensor output is fed to Atmega8 microcontroller. To know the cylinder heaviness, load cell utilized which helps to booking new LPG incorporated with IOT. The ESP8266 WIFI component transmits the statistics to end user through text message as well as booking is automatically accepted in record gasoline numeral. This methodology is helpful to shield the human life and thereby preventing LPG blast disaster in particular area.
