A method and device to control electrical devices using motion detection are presented, through which an object inside a monitoring area which is subdivided into a pre-detection area and a detection area is successively identified as well as verified in the detection area for reducing power input in standby mode and during operation in the main cycle using distance measurements and its position consequently determined. During the course of the distance measurements, the control device is brought into a readiness state and later on into operating state. After finishing the distance measurements and determining the position of the object in the detection area, an output signal which serves to control an external electrical device is generated by a control device.
