An EMF (electromagnetic field) meter is a device used to measure electromagnetic radiation in a given area. The emf detector described in this video has a minimal number of components, which means that it is simple to make, and does not require any tuning. It works great right from the first power on.
The device is very simple to build and consists of several components:
- Arduino Nano Microcontroller
- SH1106(or SSD1306) Oled display
- and Buzzer
In addition to visual, the EMF detector also has a sound signal with three different frequencies 100, 500 and 1000 Hertz proportional to the strength of the field. This device is also sensitive to static electricity, which means it can also be used as an Electroscope.
