摘要
粮情的实时检测关系到储粮安全,温湿度是粮食储藏过程中最为重要的两个因素。为此,针对检测储粮的温湿度,系统设计了基于以AT89C52为核心控制器件,以SHT11为温湿度传感器的检测系统;为了实现远距离上位机的实时监测,采用RS232/RS485转换接口器件进行电平转化,适应PC机串口RS232电平,将数据传输到PC进行显示,并实现了在软件中的仿真。
Real-time monitoring of grain moisture and temperature are important in maintain grain quality during storage.In this paper,a digital temperature and humidity monitoring system was designed for grain storage systems based on SHT11 and AT89C52 MCU.The data processed by MAX487 is transmitted from MCU AT89C52 to a personal computer for display.
