介绍了一种新型的温湿度检测传感器AM2302在粮食储藏室温湿度监测中的应用方案。此设计以粮食储藏室温湿度为监测对象,利用C8051F330单片机,设计AM2302数字温湿度传感器采集电路和采集程序,并通过“穿墙王”SI4432无线收发模块传送给PC机,PC机采用LabWindows/CVI交互式C语言开发平台,将采集到的温湿度数据通过串口接收并实时显示在CVI界面上,并利用CVI提供的Excel Library库将温湿度数据每隔一段时间就保存在Excel中,便于用户查找和记录。
A new type of temperature and humidity detection sensor AM2302 in food storage room temperature and humidity monitoring program. This design uses the temperature and humidity of the food storage room as the monitoring object, uses the C8051F330 microcontroller to design the AM2302 digital temperature and humidity sensor acquisition circuit and acquisition program, and transmits it to the PC through the “through the wall ” SI4432 wireless transceiver module, PC using LabWindows / CVI interactive C language development platform, the collected temperature and humidity data received through the serial port and displayed in real-time CVI interface, and the use of CVI Excel Library library to provide temperature and humidity data stored in Excel from time to time, easy User search and record.
