摘要
本文设计研究了一种便携式环境参数检测仪。该仪器以AT89C52单片机为核心,选用相应的传感器并设计了采集电路,实现对温度、湿度和CO浓度的检测,可显示、查询相关参数,实现人机交互功能;湿度查表子程序中,把划分的湿度小区间视作线性区间,简化MCU计算,提高了系统工作效率。
In this paper,a portable environment parameters detector was designed.It mainly designed with the adoption of the MCU AT89C52 together with special sensor, It can detect the temperature, humidity and CO concentration by designing the proper acquisition circuit and it can also work interactively when displaying, and requesting relative data. To improve the system＇s performance, the linearization method was utilized for those small space intervals on the humidity look-up data designing to simplify the MCU processing.
