Design of the High Ratio of Function and Price of Humidity

In order to raise the ratio of the function and price of the control,the intelligent gauge of function diversification isn't used during the design,but by the humidity sensor the degree of humidity is converted to the homologous electric voltage signal,and then to numerical signal,which is sent to the microcomputer,finally displayed numerically and controlled.The function of the gauge designed is single,while the application is wide,and the ratio of the function and price is very high.
