1. A sensor, comprising:
a control unit, configured to analyze data available to the sensor, the data comprising measurement data of the sensor and data from an external data storage, the data from the external data storage comprising information on an expected duration of a power saving mode, and to generate power management data based on the analysis of the measurement data of the sensor and the data from the external data storage; and
a wireless module configured to transmit measurement data,
wherein the control unit is configured to use the power management data to select a power saving mode of the wireless module from a plurality of available power saving modes, and to control the times of measurement intervals of the sensor,
wherein the control unit is configured to select extended discontinuous reception (eDRX) as the power saving mode if the expected duration of the power saving mode is a first time span,
wherein the control unit is configured to select Power Saving Mode (PSM) as the power saving mode if the expected duration of the power saving mode is a second time span which is longer than the first time span, and
wherein the control unit is configured to select disabling the wireless module as the power saving mode if the expected duration of the power saving mode is a third time span which is longer than the first time span and the second time span.
