Capacitive Humidity Transducer
Kenneth W. Misevich · IEEE Transactions on Industrial Electronics and Control Instrumentation · 1969
Of all the basic environmental variables, only humidity has resisted simple, reliable measurement. Hygrometric elements have always had limitations in their useful application, especially with regard to their inability to be stable and durable. Here, the rationale behind the development of a capacitive-type sensor is presented along with the functional and electrical characteristics to encourage confidence in the basic mechanism.
