Hi.
Been researching EMF meter with Arduino.
Seems to be many projects that work but produce uncalibrated reading in an unknown spectrum.
Has anyone successfully calibrated an EMF meter with a standard unit such as Hz; V/m; uT
uT obviously leads into magnetics / I am hoping to achieve just eField reading to begin with.
What would be the minimum level of sophistication required for a calibrated reading...? Something like in the photo below, and then there is antenna design. I have a website link from an ‘instructable’ on antenna design for a specific range in MHz however following other tutorials using a 3.3MOhm resistor to pull the antenna to ground and the same antenna seems to produce stochastic results.
This is the perfect question to ask Mr. Google! And he comes back with lots of answers, including videos.

Good Question, very hard to answer. I typically use a spectrum analyzer. I cannot answer this question because of all the missing information. You appear to want it calibrated as well. For calibration you will need some sophisticated calibration equipment, a screen room to keep out external EMF etc. The calibration setup is very expensive. You need to define the bands you will be operating in and the levels you want to measure. You might find what you want on the ham side, such as a grid dip meter. They also have field strength meters and other equipment that may do what you want. You need to do a lot of research so you can properly define your question. This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!
