A sensor (100) for detecting particles, the sensor (100) comprising an electrode (102), a sensor active region (104) covering the electrode (102) and being sensitive for the particles, a first switch element (106) operable to bring the electrode (102) to a first electric potential (VT) when the first switch element (106) is closed, a second switch element (108) operable to bring the electrode (102) to a second electric potential (VD) when the second switch element (108) is closed, and a detector adapted to detect the particles based on a change of the electric properties of the sensor (100) in an operation mode in which the electrode (102) is brought to the first electric potential (VT) and an operation mode in which the electrode (102) is brought to the second electric potential (VD). |
