Summary:A sensor and a sensor network. The sensor comprises a switchable RC low-pass filter, an evaluation unit, a synchronization unit, and a two-wire interface. The two-wire interface is configured to be connected to a control device to receive an electrical supply voltage, provided by the control device, for supplying the sensor with electrical energy, to receive sync pulses superimposed on the supply voltage for synchronizing a data transmission from the control device, and to transmit data to the control device. The RC low-pass filter generates a reference signal by low-pass filtering an input signal, and to have a first time constant in a first mode and a second time constant in a second mode, wherein the second time constant is shorter than the first time constant. The evaluation unit stabilizes the reference signal by alternately switching the RC low-pass filter into the first mode and into the second mode.
