Simulation products have been gradually replaced by digital products, and has become more and more convenient to use. Although the market today have a lot of environmental testing, but the need for people to learn living environment tester rarely, therefore devised a simple and practical environment tester is very meaningful.The temperature of the environment by collecting circuit tester, humidity acquisition circuit, the light intensity acquisition circuit, multiplexer circuit, A / D converter circuit, LCD dynamic display circuit, clock circuit, reset circuit and single chip processor, microcontroller-based digital signal The high sensitivity and controllability, temperature and humidity sensors can generate analog signals, and A D analog to digital converter chip performance /, designed a basic 8051 system as the core of a detection system, the system by the signal acquisition, signal analysis and signal processing three-part.Hardware welding, static and dynamic debugging and write and modify the program, works to achieve a good final test tasks and requirements.目录前言.............................................................................................................................1第一章 系统设计21.1.2 湿度传感器的选择4第二章 硬件设计62.2 信号分析与处理72.2.1 A/D转换72. 2. 2单片机MCS5182.2.3工作方式112. 2. 4系统时钟的设计122. 3显示电路13第三章：软件设计14致谢......
