一种基于ARM的无线便携式空气质量检测仪设计与实现

Design and implementation of a wireless portable air quality detector based on ARM

针对传统环境检测仪布线复杂、可靠性低且成本高的缺点,设计了一种空气质量检测仪。该检测仪分为发送端和手机终端两部分所组成,发送端首先通过传感器采集5种空气质量参数,然后再上传给STM32F103进行分析和处理,在利用液晶屏进行显示的同时,对于处理后的数据进行打包,并且通过无线模块发送至手机终端进行显示。实验表明,该系统具有结构简单、工作稳定,数据误差在±0.5%以内,并且能够实现将数据进行共享以及大范围实时监测空气质量。

In view of the disadvantages of complex wiring,low reliability and high cost,a kind of air quality detector is designed.The detector consists of transmitter and mobile phone terminal consists of two parts,the sender first through the sensors to collect 5 kinds of air quality parameters,and then upload to the STM32 F103 analysis and processing,display at the same time in the use of the LCD screen,the processed data is packaged and sent through the wireless module to the mobile phone terminal display.Experiments show that the system has the advantages of simple structure,stable operation,less data error±0.5%,and sharing data and monitoring air quality in a wide range.
