A mechanism with wireless receiver that can monitor and detect LPG leak, trigger an alarm, an exhaust fan and solenoid valve at dangerous levels was designed. Wireless receiver was made so that the user can monitor the leak remotely.
The sensor was calibrated to be as accurate as the MIRICO LPG Gas Leak Detector. Through t-test it is assumed with 95 % confidence that the reading between the leak detector and the sensor was statistically equal. The system designed was also efficient in decreasing the amount of concentration down to the safe level. The wireless receiver was tested and found to operate with the range of 25m for indoor and 100 meter for outdoor.
The design can be implemented in other establishments since LPG leak does not only occur in the house, but it also prevalent in facilities wherein gas cylinders are stored and in cars that use LPG as fuel. It is also suggested that, the design be integrated with a Global System for Mobile Communication (GSM) Module, so that once the alarm is activated and the mechanism fails to stop the leak, the nearest hospital, fire station or a relative
