LPG gas leakage leads to various accidents resulting in both material loss and human injuries. The risk of explosions,
firing, suffocation are based on their physical properties such toxicity, flammability, etc. The number of deaths due to gas
cylinder explosions has been increasing day by day. The reasons for such explosions are worn-out regulators, old valves and
lack of awareness in handling gas cylinders. So to preventing such type of accidents we are going to develop an Arduino based
LPG gas leakage detection and alert system. If gas leakage occurs, the system will detects it and makes an alert by buzzing the
buzzer attached with circuit. This system will also contain GSM module which can be used to send the alert message to the user.
GSM is a mobile communication modem and it is widely used mobile communication system in the world so with the help of
GSM module or Nodemcu we can also control the home appliances with the help of Arduino microcontroller
