Title   The Dsige of a Smart Gas Leakage Monitoring System Based on Wireless Sensor Networks

Abstract In recent years, with the application of the modern wireless communication technology,information technology and sensor technology,the Internet of Things(IOT) and its one of the most important applications——Smart Home have attracted more and more human,s attention. In terms of safety, the smart gas leakage monitoring system can enhance the security of home life,eliminate the hidden danger of gas leakage and explosion.People can experience not only a new operation platform and the service,but also a change of lifestyle.In this thesis, the MSP430F147 microcontroller produced by Texas Instruments was selected as the core processor to build a smart gas leakage monitoring system based on WSN.Comparing with state of the art,our monitoring system has two advantages.Firstly,it can detect the concentration of the gas and inform users via wireless sensor network and APP(application) on mobile phone.Secondly, we can remotely lock the gas pipeline by APP.The hardware design such as LCD and Wi-Fi module and software design of each module is illustrated in detail.The designed system was produced, assembled and debugged,and finally realized the function of gas leakage monitoring.
