摘要
现代农业生产离不开环境控制,将单片机控制和智能传感器监测相结合,提出了基于单片机的温湿度检测系统设计方案。同时,介绍了一种基于AT89C51的单片机的温度和湿度检测与控制的方案,针对被测对象的温度与湿度在不同变化范围需要不同的PID参数的特点,自动选择合适的一组PID参数进行控制。
Modern agricultural Production is inseparable from the environmental control.This system combine intelligent sensors test with mcu control.This thesis proposes a design seheme on mcu temperature and humidity testinf system.The schemes of the measure and control of the temperature and humidity based on single chip microcomputer AT89C51 is introduced in this paper.In view of the characteristics of the different PID parameters with the different temperature and humidity,selects appropriate PID parameters to control on the basis of the measured temperature and humidity,and the whole design is very clear and concise.
