Abstract
An arrangement for determining relative atmospheric humidity and temperature by means of a capacitive atmospheric humidity sensor and associated sensor evaluation electronics. The capacitive atmospheric humidity sensor has a polymer layer as a dielectric and two electrically conductive electrodes. For the temporary heating up of the capacitive atmospheric humidity sensor, one of the electrically conductive electrodes is designed as a laminar heating resistor with at least two power terminals.
