摘要

This paper introduces the basic design principle of the fully automatic integrated exhaust fan, the composition of the system hardware and the control algorithm. An exhaust fan which can detect gas automatically and work automatically is designed. It is assembled with smoke sensors, carbon monoxide sensors and exhaust fans to achieve automatic detection, automatic operation and elimination of harmful gases, and ensure people's health is not infringed.
