Abstract
With the development of science and technology, the improvement of and the living standards of the people, the people are improving constantly in indoor living environment, the air conditioner , intellectual temperature device , high-tech products of such people's living conditions of a series of improvement as the purifying device ,etc. in the room have appeared. But this can not meet higher and higher life demands of people , some people propose the demand for the humidity, this text is just on this basis, design one on the basis of intellectual humidity control system which 89C51 MCU controlled.
This system USES a relatively sophisticated detection circuit, automatic, accurate detection of environmental air relative humidity, and will test data transmission, by frequency to processor (AT89C51), and then through the software programming, the current environment of relative humidity value conversion to a decimal number, then through digital tube to show, And, through the software programming and design can be set according to their own air relative humidity automatic adjust current environment of relative humidity: when indoor air humidity is high, the automatic control system startup dehumidifiers, reduce indoor air water vapor to reduce air humidity purpose, When indoor air humidity is too low, automatic control system, the increase of air start humidifier vapor, in order to achieve the goal that increase humidity, air humidity keeping in the ideal state, Keyboard Settings and adjusting the initial value, additional humidity in the design of a process, considering the anti-interference, increases the power system stability.
Based on the relative humidity controller based on single chip design, deepen our understanding of the sensor technology and testing technology, consolidate the SCM's knowledge of the system, and the professional review learned knowledge.
