Electromagnetic fields naturally and invisibly exist around us. We have been gradually engulfed by them due to our dependency on technology. Even with concerns that continuous exposure to power and communication fields has devastating effects on our health, we are increasing our demands for it every year. This increase does not seem to end or slow down. With our desire for new technology and with the increasing population, we are potentially placing ourselves in more and more danger. This paper focuses on an interesting and novel approach in detecting Extremely Low Frequency (ELF) magnetic power fields using a Wireless Sensor Network (WSN). This approach is introduced by the work in progress towards a sensor that will perform data collection on ELF magnetic fields for the forthcoming research.
