A kind of macromolecule humidity instrument based on integration method of frequency and period measuring is presented in this paper. This method translates the relation between the variation of the resister of sensor and humidity into that of frequency and humidity. It determines the humidity by the input signal, which is measured through alternating the method of frequency and period measuring according to the value of signal measured last time. Emphasis is put on how to apply and implement the integration method of frequency measuring and period measuring in this paper. This method has the features of simple construction, adaptation to remote metering, strong ability of anti-interference and wide measurement range.
