| 1. A method for operating a particle sensor for recording particles in an exhaust gas flow, the method comprising:
ascertaining at least one measure of the exhaust gas flow at the particle sensor;
in a valuation of a particle sensor signal made available by the particle sensor, taking into consideration the measure for
the exhaust gas flow; and
in response to an increasing gas flow, providing an increase in a sensor sensitivity.
