ABSTRACT:
A sensor system has a support that extends along an observation zone, a row of detection subassemblies arranged one after another on the support and having subcircuits for capturing detection events within respective observation subzones defined by the respective detection subassemblies, and a base circuit on the support. The detection subassemblies are controlled with an alternating voltage having a frequency that forms a carrier frequency based on which a signal dialog occurs between the subcircuits and the base circuit.
