A capacitive sensor (12) for a vehicle seat (10) comprises an antenna electrode (16) and a control and evaluation circuit (14) operatively connected to the antenna electrode. The control and evaluation circuit is configured to operate in a first mode of operation, during which it measures alternating electrical current flowing between the antenna electrode and ground. The capacitive sensor comprises a seat frame connector (38) for connecting the control and evaluation circuit to the seat frame (20) of the vehicle seat. The control and evaluation circuit is configured to operate in a second mode of operation, during which it measures electrical current flowing into the seat frame connector.
