Smart valve control system for LPG cylinders using IoT

Liquefied Petroleum Gas (LPG) is one of the most widely used domestic fuels. It is consumed in households for cooking and is also used for industrial purposes. Being a commonly used fuel, it is prone to occasional accidents in cases where the gas cylinder nozzle is not closed properly during the night, or when the user is out of the house. This may lead to safety hazards, causing damage to life and property. Currently, cylinders are operated only physically by the user. It is human nature to be occasionally inattentive, forgetful or negligent. Sometimes when the user leaves their home, they may forget to close the cylinder nozzle properly. This causes gas leakages, which are dangerous. This work is focused on building a system that uses Internet of Things to control the opening and closing of gas nozzles or valves using a mobile or web application remotely. The user can check if their home gas valve is open or closed on the application, and can use it to either close or open it as per their need. This way, they have more control over their home, contribute towards reducing wastage and create a safer environment.
