【Abstract】 WT5”BZ]: Al 2O 3 moisture sensor is a new type water sensor, which can measure minim water. There is very important application in the drying process of the materiel and in the monitor & measurement of the milieu.The theory of this kind of sensor is introduced. The structure and design of the measure instrument on-line based on the single chip processor is discussed.The symbol adjust circuit of the sensor and the 8031 single chip microcomputer system are designed and the main program flow chart is described.The instrument has important meaning for the real-time on-line monitor & measure of the drying process,which has been used in the electric material drying experiment and the anticipative result has received.
