Abstract
While “information age” the arrival, obtained the remarkable progress as the gain information method - - sensor technology, its application domain is more and more widespread, is more and more high to its request, the demand is more and more sensor technology has e weighs one of national science and technology level of development important , understood and grasps each kind of sensor the basic structure, the principle of work and the characteristic is extremely important.
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 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 which selects the 2M007 semiconductor resistance type smog sensor realization smog the examination, has the sensitivity high, responds, the antijamming ability quickly strong and so on the merits, moreover the price is inexpensive, the service life is long.
Key word: Smog, alarm apparatus, sensor
