AbstractAs human beings continue the destruction of the natural world, airpollution is becoming increasingly serious, and indoor air pollution hasbecome one of the sources of pollution and air quality testing and purificationas an indoor air purification appliances have emerged .This article describes the specific air quality testing and purification ofthe product market as well as the design of this instrument required hardwarecircuit design and software development processes. This article focuses ondesigns to ATmega128 micro-controllers core, added air quality testingmodule, LCD module, air purification module, motor drive module, WIFIphone remote control module, ADC reference voltage circuit, alarm circuit,reset circuit and power supply modules and there is contact between thecontrol and complete hardware design. Next, the operation of the processsystem and the need to achieve a specific analysis functions, design theappropriate software flow. this system design and summarizes the results wereanalyzed from intelligent systems, security, efficiency and innovation andother aspects, to the need to improve and perfect part.
