MINI PROJECTS ABSTRACT E&I/ECE/ICE/EEE-Lpg gas detection and indication

  1. 1. MINI PROJECTS-LPG GAS DETECTION WITH LCDThe gas is colourless and has a faint smell owing to the addition of achemical compound "mercaptan."In LPG (liquefied petroleum gas) cylinders, the gas regulator allowspressurised LPG to flow in its gaseous form to the burner.Highly inflammableLPG is highly inflammable and can burn even at some distance fromthe source of leakage.Most fire accidents are caused either owing to a poor-quality rubbertube or because the regulator is not turned off. Even when the stoveknob is turned off, the supply of gas from the regulator to the burneris on. If the knob turns on by accident, the gas leaks.The rubber tube, which connects the cylinder to the stove, must be ingood condition. Cockroaches or rodents are attracted to the foodresidue on the tube and damage the rubber. Hot vessels or splashingoil may also burn a hole in the tube.Once there is a gas leakage, lighting a match or switching on a lightor a fan is enough to ignite the gas and cause the cylinder to explode. 89 RANGARAJAPURAM MAIN ROAD,KODAMBAKKAM,CHENNAI-24 PL VISIT www.maastechindia.com,mobile:098402 34766
  2. 2. Electrical fires are another cause of accidents. They are caused whentoo many types of equipment are connected to the domestic powerline. The overload causes the wire insulation to melt and a shortcircuit occurs.Old light fittings and switches also cause short circuits. Unattendedirons, heater coils and other heating elements also lead to fireaccidents.Proposed Idea: In our Project we have used a LPG gas sensor for sensing theLPG Gas level and singals the human by alarming and further more,as a preventive action, the control energises a Mechanical Modelwhich is used to turn off the Regulator Knob. This is done with thehelp of a stepper motor. For Gas Detection, LPG Gas Leakage sensorsare used.The proposed block diagram is given below: Power Supply unit 89 RANGARAJAPURAM MAIN ROAD,KODAMBAKKAM,CHENNAI-24 PL VISIT www.maastechindia.com,mobile:098402 34766
