Zusammenfassung:The warning system includes, in one embodiment, an antenna which is tuned to an EMF frequency generated by the EMF radiating device. These EMF radiating devices may be televisions, computer monitors, cathode ray tubes or microwave ovens. An RF receiver and converter is electrically connected to the antenna. The converter generates a first control signal in the presence of the EMF radiation from the EMF radiating device. A motion sensor is mounted adjacent to the EMF radiating device. The motion sensor generates a second control signal when the motion sensor detects a moving object within a detection range. A switch, electrically connected to the converter and the motion sensor, receives the first and second control signals. The switch generates activation signals dependent upon the first and second control signals. A visual warning alarm is electrically connected to the switch and issues visual warnings dependent upon the activation signal. Additionally, an audio warning alarm is electrically connected to the switch and generates an audio alarm dependent upon the activation signals.
