In today’s technology-driven world, we are constantly surrounded by
electromagnetic fields (EMFs) generated by various electronic devices and power systems.
These invisible forces may influence our environment and well-being, yet they often go
unnoticed. This research introduces a user-friendly, portable device designed to detect and
spatially visualize Extremely Low Frequency (ELF) EMFs. Utilizing a Raspberry Pi Pico
as the core processor, along with a magnetometer and LiDAR sensor, the developed
radiation tester not only measures EMF strength but also maps its distribution in space.
Although testing was conducted in controlled environments using transformers and
toroidal cores rather than real-world power infrastructure, the device effectively identified
variations in EMF levels. While not intended for health diagnostics, this tool presents a
practical solution for contractors, researchers, and communities seeking to better
understand EMF exposure. The project contributes to making invisible environmental
factors more tangible, enabling safer, more informed decision-making regarding EMF
exposure in everyday settings.
