Real-time electromagnetic monitoring system is purposed to inform the general public of the electromagnetic fields data. It measures 60 Hz extremely low frequency (ELF) magnetic field in real time under transmission towers placed in the vicinity of residential areas usually accessible to general population and displays measured values on the LED screen. Comparing data between domestic and international standards and the average EMF measurement values from the variety of electronic products, it informs the general public of the electromagnetic environment surrounding the power lines and alleviate fear about EMF exposure.
