In this proposed system, the gas leakage is detected by the gas sensor MQ6 which is interfaced by arduino and automatic booking is designed and this device will be a single system with multiple applications for LPG consumers. If the gas leakage is detected by LPG gas sensor the device gets on with buzzer alarm and displaying alert message in LCD display simultaneously switch on the exhaust fan and start the DC motor, external coupling is made to turn off the gas regulator and the temperature sensor is also placed to reduce the false detection at the same time PIR sensor also placed in the home to notify about the human presence. If no person, automatically powers off at the same time the notification will be sent to the user through mobile by warning calls and SMS or Email. For automatic booking, a Load cell which is also known as pressure sensor is used to detect the weight of the gas and the weight will be displayed through LCD. If the weight of the cylinder is below the threshold level automatically the new cylinder will be booked and the delivery information sent back to the consumer through the GSM module.
