Abstract:

In daily life because of polluted air people have a headache, insomnia, allergic diseases, respiratory diseases, etc. Air Purifier is also called "air cleaner" or "air sober machine". It refers to an equipment which can adsorb, decompose or transform all kinds of air pollutions,and volatilize an anion to improve the indoor air quality. In order to achieve the purpose of the microcomputer digital control of system, air purifier is designed with a single chip to reduce the artificial control. The single chip microcomputer is regarded as the core circuit part of the whole control system, the function of which is control all components of the air purification. Air purifier equipment consists of dust sensors, anion generator unit, fan module components and 4x4 matrix keyboard. Software program mainly includes: the display program, keyboard program, the clock program. This design aims at starting subsequent circuit module automatically through real-time control of air quality, achieving the function of air purification.
