摘要
针对生产加工及库房等场所温湿度的检测与控制,设计了一种基于数字温湿度传感器的温湿度测控系统。为了实现对温湿度的可靠采集与传输,在对传感器数据进行读取及通信时采用了CRC校验技术,并且设计了硬件电源监视复位电路,对系统电源波动引入的干扰起到了很好的抑制作用,使系统的可靠性得到大大提高。
Aiming at the measurement and control of temperature and humidity in the site of working place and storeroom, a measurement and control system is designed based on digital temperature-humidity sensor In order to ensure the reliable collection of temperature and humidity, the CRC technique is adopted in the collections and communications of sensor＇s data. Meanwhile, the power-watch reset circuit is designed for the inhibition of the interferences caused by system power fluctuation , which make the system reliability enhanced greatly.
