Smart LPG Gas Detection and Automatic Booking System for Home Safety Using IoT Platform

Liquefied petroleum gas (LPG) is routinely used by homeowners, but many are unaware of their daily usage rate and the framework of time in which they must schedule a refill. In homes and other places where residential gases are used, leakage creates a serious problem. So, we offer an Internet of Things (IoT)-based system that keeps track on number of LPG cylinder related variables and notifies the user via a mobile application. Here, using a sensor known as a load cell, the amount of gas present in the cylinder is detected. The amount of gas still in the cylinder is continuously updated in the user’s app, and the user is notified through the buzzer and the mobile app, respectively, when the gas level falls below the threshold value. Another safety feature included in this home automation system is to alert the user about the gas leak via a buzzer and a mobile application. Also, it deactivates the gas control knob to halt additional leaks at their source. Our mobile application can also be used to activate and deactivate the gas valve. This device can be used as an assistive mechanism for LPG gas leakage detection and automatic booking system for home safety purposes.
