摘要
利用单总线数字式温度传感器DS18B20和数字式湿度传感器LTM8901来检测温室环境的温度和湿度,提高检测的精度,降低了干扰;并且利用FLASH芯片作为数据的移动式存储单元,方便了农户的数据转移,降低了成本。可以将其与PC通讯,将数据转移到PC机界面,实现对数据的存储、数据的回归分析和曲线显示等功能,为后期的温湿度控制、获得高产提供理论基础。
The system uses 1-wire bus digital temperature sensor DS18B20 and digital humidity sensor LTM8901 to realize the detection of the temperature and the humidity for greenhouse, raise the accuracy of the measurement and reduce the Interference. And uses the flash chips as the portable memory unit, it is convenient to transfer data for user, and the cost is less. The flash chips can be connected with PC to transmit data to the window of PC. The system realizes the function of the memory and data regression analysis, and the display of the curves. It provides the theory regularity for the detection of the temperature and humidity and getting higher produce. [
