LPG Leakage Detection and Prevention System using IOT

Abstract

Security is primary concern for everyone. There are numerous ways to give security at homes or in diligence. The main end of this design is to continuously monitor the house or diligence and if any fire accidents occur, the system should warn the temptress. A gas detector will be fixed in the house or in an assiduity. The status of the detector will be continuously monitored by the microcontroller. Whenever the status of the detector changes, microcontroller detects this and incontinent cautions the temptress. The main end of this design is to continuously cover the status of the gas sensor and if its affair triggers, the controlling unit activates the buzzer to warn the surroundings and shoot the SMS to the concern authorities to take necessary action. It's also having weight detector whenever the gas position is less automatically it'll shoot the communication to gas agency for booking of new gas cylinder, and it'll automatically turn off the power of the house. The gas sensor will be connived with the microcontroller through transistor since the microcontroller cannot read the affair of the detector directly. The microcontroller cannot drive the buzzer and cannot give the current needed for the buzzer. Therefore, the buzzer will be connived to the microcontroller through transistor. In this case, the transistor is responsible for passing the current.
