In order to enhance to the sensor understanding and the understanding, in particular to the smog sensor thorough research as well as its usage and the use, based on practical, widespread and the model principle has designed this system.This article used the monolithic integrated circuit union sensor technology to develop has designed this smog supervisory system.. The present paper take leaves the minor smog sensor and the monolithic integrated circuit technology unifies as the core and with other electronic technology, designs one kind of technical level good smog alarm apparatus.In which selects the 2M007 semiconductor resistance type smog sensor realization smog the examination, has the sensitivity hi
