I'm planning to use a Hall sensor for a gimbal in my Arduino transmitter. Will the magnet associated with the Hall sensor interfere with radio signals?
Impossible to say for certain on the basis of so little detail from yourself, but I'm pretty sure the answer is no.
I'm planning to create a joystick for my Arduino transmitter. Initially, I tried using a 10k potentiometer, but the precision wasn't satisfactory. Now, I'm considering using the AS5600 module instead of the potentiometer. I'm concerned whether the magnet in the AS5600 module will interfere with the signals transmitted by the NRF24 ML01DP5 module, which I'm using as a transceiver in both the transmitter (TX) and receiver (RX) units.
No
Hall sensors do not emit RF energy.
Magnets do not typically interfere with radio signals, unless you have a strong magnet placed adjacent to the transceiver.
Will a strong magnet affect the signals?
How would that interfere?
I can understand that if the magnet is moving rapidly and there are circuit components/conductors within it's field, then currents will be induced, causing electrical and electromagnetic interference. Can a stationary magnet cause interference?
I don't think so, it would only be if the magnet was in motion.
I read a little more about it:
The interference would be minimal.
Magnetic fields produce a very small gravitational field, as the magnetic field itself is a source of gravity. This can interfere with EM waves, like radio signals, but wouldn't do much.
general relativity speaks a bit about it.
Superposition principle states that EM waves can travel through static fields with no interference.
I can't imagine what we are talking about would be of any concern to the OP
I apologise, I didn't state that the interference would be miniscule at best in my first post
Not enough for you to be concerned about it. Go for it!
ok, thank you

Einsteins equation E=mc2 states that energy and mass are interchangeable
Therefore, any form of energy contributes to the gravitational field. The energy in this magnetic field is a source of gravity, as is energy in any field
I meant source, not force lol
Why does the Big magnet at the back of a speaker build into a radio not interfere with the radio signal?
According to @chrisd79, it does. Assuming he is interpreting old Albert's theory correctly. But the scale of that interference is inversely proportional to the speed of light squared, so I don't think we need to worry about it much ![]()
I mentioned in post #7 that it is miniscule at best, so it doesn't make much of a difference at all. I forgot to mention that in my original post
I just didn't want to say that it would cause absolutely 0 difference at all lol. As mass can be converted into energy, energy can also be converted into mass, and all mass has it's own gravitational field. But as we're not building a nuclear bomb or recreating the big bang, there isn't a lot of energy. So yes, nothing to worry about in this case...
Remember, we all share space on a very large magnet and still enjoy the use of radio signals.
And we wouldn't be here without that magnet!
