Design of Temperature and Humidity Measurement System on Measurement and Control Equipment Based on SHT11 Sensor

针对测控设备远程操控建设的需要,在原来以Xilinx公司FPGA芯片为核心器件的远程加电控制板平台上,研究了基于SHT11温湿度传感器和FPGA技术的测控设备工作环境温湿度监测系统。使用SHT11传感器实时采集温湿度数据,同时采用X3CS200芯片进行数据存贮和计算等处理,通过外围扩展电路设计了一个温湿度检测系统。该系统实现了对环境温度参数的实时采集与传输,测试结果表明系统测量精度高、可靠性强,且具有体积小、操作方便等优点。

To meet the demand of construction of remote measurement and control equipment,and on the remote power control platform based on the Xilinx FPGA chip as the core device,a temperature and humidity measurement system for measurement and control equipment based on SHT11 sensor and FPGA technology is presented in this paper. SHT11 is used in this system to collect temperature and humidity data.And X3 CS200 is used for data storage and computed.A temperature and humidity detection system with multiple functions is designed by the expansion of peripheral circuit. The system can acquire real-time parameters of the ambient temperature and humidity on the platform. Experimental results show that the system features high measurement precision,high reliability,small volume and convenient operation.
