摘要
在对国内外同类产品分析研究的基础上,作者设计了一种基于单片机控制的温湿度控制仪,从硬件和软件两方面设计并实现了对温湿度的精确控制,该控制系统主要采用AT89S51、LED显示器、SHT11等芯片,并对其组成以及硬件电路进行了详细的介绍,阐述了温湿度控制系统的工作原理以及设计方法。最后通过系统软硬件联机调试,实现了温湿度信号检测与控制,达到了预期要求。
Based on the analytical study to the domestic and foreign similar products,one kind control meter of temperature and humidity was designed which controls based on microprocessor.By designing the hardware and the software,accuracy control of the temperature and humidity was realized.The control system mainly used AT89S51,LED monitor,SHT11,and so on.Its composition and the hardware circuit were introduced in detail;the working principle and design method of the temperature and humidity control system were explained.Through the system software and hardware on-line debugging,the signal detection and control of temperature and humidity are realized and the result reached the expected requirements.
