摘要
介绍了温湿度监测系统的基本组成和工作原理。系统采用温湿度集成传感器采集温度和湿度,并通过nRF905射频模块与计算机进行通信,同时把相应的时间、温度及湿度参数每隔一定时间存储在AT24C1024芯片上,通过射频传送给计算机。经使用证明,系统具有良好的可靠性和较高的精度。
The basic composition and working principle of temperature and humidity test system were introduced.The monitoring system detected the temperature and humidity with an integrated sensor,and communicated with computer through nRF905 chip.It saved the data of time,temperature and humidity by AT24C1024 chip,and sent all the stored data to the PC through RF.It was proved that the system had better reliability and higher precision in practice.
