Luequefied petroleum gas leakage monitoring and control system.

Abstract

LPG is a flammable mixture of hydrocarbon gases which is used as a source of energy for cooking in many homes in the world.in Uganda, the use of LPG is increasing due to its reliability and low cost compared to other sources of energy like HEP. However, since this gas is highly flammable, if not handled with care it can be of great danger to people’s lives and property. This gas is heavier than other natural gases like air and so when it leaks; it does not easily disperse and may lead to suffocation when inhaled and explosions when its concentration in air rises beyond. The currently used LPG cylinders do not have an automated mechanism for detecting leakages and automatic control of these leakages. This has led to increase in number of home accident cases related to LPG leakages.in this system, MQ-6 gas sensor is used to detect any leakages in the horse pipe and the system automatically turns off the gas supply to the cooker so that gas wastage is minimized. This also controls the risk of explosion which can lead to fire outbreak. AGSM modem is used to notify the user about the leakage status so that the necessary actions are taken to avoid danger. This system will reduce the increasing gas leakage related accidents, save people’s lives and property.
