Electromagnetic field meter part 1

This project can show how strong is electromagnetic field in your place. In Polish norms and documents I saw that the maximum power from GSM Base Telecomunication Stations  is 2 Watts EIRP. In first part of article I will show you fundamentals about this electronics project.

In Polish law we have a specification: 7V/m is the maximum of the intensity of the electromagnetic field for 800MHz to 2,2GHz.

In the shops we can find many types of meters, but they are so very expensive.

I decided to design simple devices to measure 800 MHz to 2,2 GHz with bluetooth, display and li-ion supply and cheap antennas . So in first step I created a simple prototype modules

To be continued 🙂
