摘要
针对工业环境中需要实时检测温湿度的问题,提出无线射频温湿度测量系统的设计方案。详细阐述了系统的设计思想、硬件结构和软件的设计方法。系统采用C8051F020作为基础,并结合nRF2401射频芯片以及温湿度传感器SHT21S,可以定时采集和存储外部温度湿度数据,能够通过无线射频识别通信上传数据并对其进行相应的分析和处理。该系统具有较高的实用性和可靠性,成本低,功耗低,具有良好的应用前景。
A kind of temperature/humidity sensor collection system is designed and implemented which aims to detect temperature and humidity real-time of industrial environments. The hardware structure and the software design method of this system are given in details. The system controls the work based on the C8051F020 microcontroller, and realizes signals of sensor modulation and demodulation with the RF chip of nRF2401 and temperature/humidity sensor SHT21S active RF[D. The system can collect and store the data of temperature and humidity periodically, upload the data through the communication of RFID, and analyze and process the data. The system has broad marketing perspective since it features of high practicability and high reliability, low cost and low power.
