Automatic LPG Leakage Indicator & SMS

Nowadays, security is the major problem in many

fields due to robberies, fire accidents and blasts due to LPG gas leakage. At present, LPG gas can be used in the car, in the storage tank or service station. But, due to some reasons the LPG gas might leak from the gas cylinders, this may cause the cylinder blast, damage the house and risk of a life to the living persons in the house. The fire ignite can be occurred due to many reasons such as an electrical , oil lamps or candles kept inside the house. Sometimes fire accidents are very small, but if proper action is not taken to control the fire, then it can spread in complete house. To overcome this problem, an LPG gas sensor is used to detect the presence of a dangerous LPG gas leak in various places.





An LPG gas sensor is a one kind of device which is used to sense the presence of a hazardous LPG gas leak in service station, cars, storage tanks and homes.This sensor is attached to an alarm circuit to give an alert to the operators through a buzzer sound in the area where the gas leak is occurring.The LPG gas sensor is also used to detect cigarette smoke,toxic gases, combustible, propane, iso-butane and LNG.


An LPG gas is a versatile fuel used in homes, but the leakage of LPG gas could lead a disaster. To aware of LPG gas leakage and avoid any mis happening there are different products to notice the leakage. Here we have designed an Arduino microcontroller based LPG detector circuit. Whenever LPG gas leakage occurs,then this system notices and gives an alert through the buzzer which is attached to the circuit. The entire system is easy to design who have some basic knowledge of electronics and programming,
