摘　　要：介绍了一种基于AT89C52单片机为控制核心的图书馆环境温湿度检测仪,实现了系统的温、湿度检测电路和LCD实时显示电路等硬件电路的设计。现场检测的试验数据与专业检测设备测试方法所得的数据比较结果表明,以所提方法为关键技术所设计的图书馆环境温湿度检测仪温度测量精度为±0.5℃,相对湿度测量精度为±1%RH,满足现场环境检测要求。系统运行可靠,结构简单,性价比高。It is introduced an environment temperature and humidity detector in library based on the AT89C52 microcontroller. The hardware circuit including temperature detecting circuit, humidity detecting circuit and LCD display circuit are designed and realized. The comparison of the measuring data by the new on-site verifying method and other measuring methods is given. The result shows that the measurement precision of the temperature and humidity are respectively ±5 ℃ and ± 1% RH. The system based on the proposed method can meet the on-site environment test requirement. This device has obvious advantages such as reliable performance, simple hardware, cheap price and good stability.
