摘　　要：设计了一个粮仓温度湿度监测系统,从机采用温湿度传感器SHT11对温度、湿度进行采集后通过无线模块PTR2000发送,主机接收后计算出温度、湿度值显示在液晶屏上,无线通讯对发送数据进行CRC校验提高了数据传输的可靠性。系统发射部分以AT89C2051为核心,包括采集模块,无线发射模块;接收部分以AT89S52为核心,将无线接收,液晶显示等模块结合起来,该系统可广泛应用到粮仓等场合中。The design of a wireless temperature, humidity collecting device, the device through the integration of temperature and humidity sensors SHT11 granary and other places on the temperature and humidity for the collection, and then the data will be collected in accordance with a certain degree of agreement sent through the wireless module, the receiving party to receive unpack the data to calculate the temperature, humidity and the value displayed on the LCD screen. AT89C2051 launch system for the core parts, including temperature, humidity collection, wireless transmitters. AT89S52 for receiving a portion of the core of the wireless receiver, combined with liquid crystal display, through appropriate software and hardware to deal with anti-jamming design of practical, small-scale collection of wireless temperature and humidity system.
