Design and implement the Hardware of Circuit control system of Indoor Air-purifier

摘要

In this paper,a new type concept design of air purifier using UV disinfection as the main means of sterilization has been proposed based on the background of development of indoor air purifier. On this basis,the overall function requirements of the house purifier has been analyzed.The working principle of the overall framework and structure of the control system has been designed.Atmega 128 of AVR microcontroller is the core of the control system.Through the microcontroller has controlled the main woking parts of the air purifier,which formed the smart circuit operating system.Meanwhile,the design and feature implementation of power control circuits,sensor data acquisition, LCD circuit and UV lamp control module circuit has been described in detail.
