摘　　要：介绍一种以数字温湿度传感器SHT15为核心的智能温湿度数据采集系统。系统采用具有高速A/D转换、加密性强和解密难度高等优点的芯片STCLE5A32S2,在阐述系统硬件组成、通讯和数据采集软件的基础上,通过传感器采集温度和湿度信号,并通过A/D转化成数字信号,然后再输入给计算机。经过处理后,计算机向温度、湿度控制电路输出数字信号来控制下位机的操作。该系统具有液晶显示、数据监控、数据存储和低功耗等功能及特性,可以广泛应用于各种温、湿度智能控制系统。This system uses the STCI.E5A32S2 sensor as the core, as it has the strengths of high speed in A/D conversion, strong in encryption and difficult for decryption. On the basis of elaborating the system hardware, communications and data acquisition software, the temperature and humidity data were acquired through the sensor SHT15 and transferred into digital signal by A/D, which was then put into the computer. After processing, the computer output a digital sig nal into the temperature and humidity control circuit to control the lower machine＇s operation. The system has data monitoring, data storage, low power consumption and otber functions witb a liquid crystal display, and can be applied in kinds of intelligent temperature and humidity control systems.
