基于nRF905的实验室温湿度监测系统研究

Laboratory Temperature and Humidity Monitoring System Research Based on nRF905

摘要: 本文以SHT11数字式温湿度传感器为基础，设计了以nRF905无线射频传输模块和AT89C51单片机为核心的由上位机和下位机两部分构成实验室温湿度监控系统。本系统的上下位机之间通信采用自行研制设计的RS-232接口电路。经过测试实验证明，该系统不仅具有精度高、操作方便等特点，而且具有良好地实时性与稳定性。

Abstract: This paper SHT11 digital temperature and humidity sensors as the foundation, the design with nRF905 wire-less rf transmission module and AT89C51 single-chip microcomputer as the core by upper machine and lower machine two parts constitute a laboratory temperature and humidity monitoring system. This system and communication be-tween a machine developed by the design of the RS-232 interface circuit. After testing experiments show that the sys-tem not only has high precision and easy to operate, and other characteristics and has good real-time and stability.
