Research On The Measure And Control System Of The Temperature And Humidity Based On Single Chip Microcomputer

The singlechip microcomputer is required extensively in measurement and control systems and the temperature and humidity need to be surveyed, controlled and maintained by a system frequently. 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 mea-sured temperature and humidity, and the whole design is very clear and concise.
