Abstract

A sensor adapted for connection to a bus and a method for supplying power to a sensor connected to a bus are described, which serve to minimize the power consumption of a sensor connected to the bus. To this end, power for a sensor is stored in an energy storage device in a first time period and is discharged in a second time period, that is, the measurement time, in order to supply the sensor element with power. A capacitor is used as the energy storage device, and the charging of the capacitor is monitored by a voltage monitoring device.
