1. A sensor, the sensor comprising power supply terminals for connecting a power supply for powering the sensor, at least one sensor element configured for measuring an external parameter and outputting one or more results representative for the external parameter, an output buffer configured for receiving the one or more results or a processed version thereof and for applying an analog signal representative for the result or a time multiplexed sequence of analog signals representative for the results on a sensor terminal, and a control circuit configured for obtaining an ID of the sensor, and for receiving a trigger signal, and for determining whether the trigger signal matches the ID of the sensor, and for enabling the output buffer during a predefined period when the trigger signal matches the ID of the sensor.
