Abstract:
The objective of this paper is to monitor the Liquid Petroleum Gas (LPG) leakage to avoid fire accidents providing house safety feature where security has been an important issue. The system detects the leakage of the LPG using gas sensor and controls the overall operation using LabVIEW software. When the system detects the LPG concentration in the air exceeds the certain level then it immediately alert the people by activating the alarm which includes the LED, buzzer simultaneously and shuts off the solenoid valve.

Keywords: LabVIEW, gas sensor, gas detection, gas leakage prevention
