Long-term tests of capacitive humidity sensors
Gert J.W. Visscher, J.G. Kornet · Measurement Science and Technology · 1994
Capacitive air humidity sensors have emerged in increasing numbers, makes and qualities. Of all hygrometers available at present, it is estimated that 70-75% employ a capacitive type of sensor. In this paper the results of outdoor experiments over a period of more than one year are summarized for most of the commercially available types.
