Abstract: Liquified petroleum gas (LPG) is one of the most popular home cooking sources in Brunei and other parts of the world where gas price is cheaper than electric price. However, LPG is highly inflammable and can easily cause fire and explosion if there is a leakage. When the gas finishes at an odd time, it will be difficult to order and get a new cylinder. There are two main objectives of this IoT-based research project. The first one is to monitor the usage of the gas and place an order through a mobile application when the gas level goes below a threshold value. The second one is to detect any gas leakage and close the knob of the cylinder when the gas leakage level goes above a threshold value and activate an alarm. This system also sends an automatic alert notification to the user through the mobile application. Apart from the mobile application, a simple web interface was also created to record the values from the sensors.
