Abstract: A sensor arrangement including a control circuit is disclosed. In at least one embodiment, at least one sensor electrode can be charged and/or discharged therewith and a comparator unit for the comparison of a provided voltage for the at least one electrode with a reference voltage. A duration necessary for the charging/discharging of the at least one sensor electrode is determined, whereby, from the determined duration, it is determined whether a sensor event, in the form of a hybridization between trap molecules and the particles for recording, has occurred.
