We have equipped our security system with gas detection sensors. So that in case if there happens to be a fire or by chance there is a gas leakage in the house that can result in fire, a vent on the roof opens automatically so that the leaking gas flows outside the house and does not cause fire or explosion. This could be an efficient way of preventing destruction caused to lives and liabilities caused by it. This is very useful for people who are usually away from home, as it sends an SMS to the owner stating "EMERGENCY; GAS LE ALERT"who is unaware of the fire.
