Design and research of Air-purifier Control System based on
ATmega128 microcontroller
Abstract

With the development of the living standard of the people and the increasing
deterioration of the environment, the indoor air pollution is getting more and
more serious, which can destroy the living environment and harm people’s health
directly. So how the indoor air could be purified efficiently has been attracted by
a lot of people, also been a very important research subject in the environment
protection.
In this paper a new air purifier is researched and designed which can provide
an answer to purify the indoor air and provide continuously fresh air. The
hardware and software design, applied in this new air purifier control system
which can kill the bacteria by ultraviolet radiation, program implement and the
analysis of key program is discussed in the paper.
The control system for this new air purifier is designed and developed based
on the ATmega128 core processors of AVR microcontroller which is form Atmel
Corporation. According to the standard of the microcontroller development, the
overall design plan for hardware and software is created based on the analysis of
system functional requiremen
