基于ARM智能空气检测与净化器的设计

摘要

为了满足人们对室内空气质量的需求,设计一种智能空气检测与净化器.该装置以STM32F103RCT6单片机为核心控制器,采用PM2.5传感器、温湿度传感器、甲醛传感器、有害气体传感器等对空气进行检测,通过等离子和负离子发生器产生大量的等负离子,利用等负离子的吸附和中和反应达到除尘、杀菌等作用,使空气得到净化.该装置通过WiFi连接入互联网,使用手机APP实现设备的数据查看和控制.实验表明,该设计具有功能化,智能化,能够实现远程查看数据以及控制设备的能力.%In order to satisfy the demand for indoor air quality,an intelligent air detection and purification device was de-signed. The STM32F103RCT6 is taken as the core controller of the device,the PM2.5 sensor,temperature-humidity sensor, formaldehyde sensor and harmful gas sensor are used in the device to detect the air,and a mass of plasma-anions are generated through plasma and anion generators. The adsorption and neutralization reactions of plasma-anions are adopted to eliminate the dust,perform the sterilization to purify the air. The device is connected into Internet through WiFi,which can check and con-trol its data by means of APP embedded in mobile phone. The device is a functional and intelligent one,and can check the data and control the appliance remotely.
