Design on A New Portable Gas Detect & Alarm Device

Dang Liqin

Abstract

A new portable gas detect alarm device which is controlled by Single Chip Micyoco is proposed in this paper. With utilization of intermittent working mode of gas sensor in this device,as a result,the battery power off time can be postponed. Then the charging frequency can be reduced. So the life of alarming device can be prolonged. Further more,the traditional battery is replaced by lithium battery. The volume of this device can be reduced ulteriorly,which also brings us the real portability of alarm device.
