Design and Implementation of an IoT Based LPG Management and Distribution System

- This paper focuses on designing and implementing a system capable of real-time monitoring of liquefied Petroleum Gas (LPG) quantity based on the Internet of Things (IoT). The quantity of LPG left in a cylinder is monitored, and this is used to forestall running out of cooking gas at critical periods or odd hours, as well as to notify the cooking gas vendor for either preparation for replacement or outright replacement. Filled four common cooking gas cylinders were used for the study. Each was divided into four thresholds of the total LPG quantity, namely: low (50%), very low (25%), critically low (12.5%) and empty (6.25%). These thresholds indicate the various points at which real-time information of the quantity of gas left is sent to both the user and the vendor via SMS employing an embedded Node Microcontroller with a Wi-Fi module for appropriate action(s) to be carried out. The system performed optimally from the results obtained in the tests carried out as the necessary information was prompted at various thresholds as designed.
