<p>A device for monitoring electromagnetic fields, comprising at least one antenna element (A1, A2, A3) for electromagnetic field measurements, a reception chain (10, 20, 30) capable of generating at least one signal which is indicative of the electromagnetic field strength measured by the antenna element (A1, A2, A3), a threshold comparator element (60) for comparing the field strength signal with a predetermined threshold level. In addition, the device also exhibits at least one of the following characteristics: a selector element (10) provided to make the device (1) selectively sensitive to at least two different electromagnetic field frequency bands, the threshold comparator element (60) presenting a selectively variable threshold level, and a communication interface (90) provided so that data can be transmitted to and/or from the device, and specifically so that the selected band and/or the threshold level used to perform monitoring can be varied selectively from a remote station. <IMAGE></p> |
