摘　　要：针对目前物流仓储管理中温湿度需分别进行测量、且功能单一的缺点,采用SHT21S温湿度传感器作为信号采集元件,以单片机AT89C52为核心,设计了一种对温、湿度同时进行检测的装置,系统通过液晶LM016L显示温湿度值,并对超过温、湿度预设值测试结果报警。系统经测试表明:温度测量精度为0.5℃;湿度检测精度为±1%RH。该系统具有结构简单、可靠性高、性能稳定、精度高等优点,适用于各种场合温湿度的检测。In view of the present logistics warehousing management of temperature and humidity are measured,and the disadvantages of single function,the SHT21Stemperature,humidity sensor as signal acquisition device,MCU AT89C52 as the core,a device for the detection of temperature and humidity,temperature and humidity values through the liquid crystal display system LM016L,and over temperature and humidity preset the test results of alarm value.System tests show that：temperature measurement accuracy of 0.5℃,humidity detection precision is±1%RH.The system has the advantages of simple structure,high reliability,stable performance,high precision,and the detection is applicable to vari- ous occasions of temperature and humidity.
