Study on the Characteristics of the Physics Innovative Experiment of Gas Sensor( MQ_3) University

In order to meet the needs of all the various for students who major in physics experiment,the new opened on gas sensors( MQ3) characteristic experiment. Through the independent design,since main solve the problem of the experiment,in order to realize the distinguished understanding process for gas sensor applications. It introduces the experimental principle,experiment content and three kinds of schemes. Finally,the measurement results are analyzed and discussed in detail.
