摘要
本设计基于单片机技术,实现温室的温、湿度自动检测与控制。设计中,以单片机89S52作为控制核心,采用数字温湿度集成传感器SHT10进行数据采集转换,以键盘输入方式进行温湿度值设定,用液晶屏实现温湿度数据的实时显示。温度与湿度的调节装置能够保障温湿度参数的变化不超过设定范围,否则报警并自动调节。系统已经在小型温室大棚中试用,完全达到设计要求。与传统的温湿度测量方案相比,本系统测量精度更高,控制更加精确,外围电路更加简洁,而且节约了人力成本。
This design is based on MCU technology,and achieves realizing automatic detection and control of temperature and humidity in greenhouse.The design takes MCU 89S52 as control core,with digital integrated temperature and humidity sensor SHT10 acquiring and conversing data,keyboard setting values,and LCD displaying current temperature and humidity.Adjusting device can ensure stable temperature and humidity within a set range;otherwise alarm and further adjustment will be triggered.The system has been used in small greenhouses and has fulfilled the tasks as designed.Compared with traditional temperature and humidity measurements,this system achieves a higher accuracy of measurement and control,a more concise periphery circuit,and a lower cost on manpower.
