Interesting, i didn't know that ESP32 has built-in hall sensor. It would be interesting to get some info about its sensitivity.

It works like shit, IMO.
r
Have you tried?

Yep. First of all, it is bad (i mean "not") documented according to technical specs. Second, a metal shield on most ESP boards gives you faulty results.
So, to use it, you should remove metal cover or use shieldless chips (like "sonoff mini diy")

But you can use it shielded with VERY strong magnets, IMO
r
Does it sense the earth' magnetic field?
AF
Nope :)
AF
Well maybe yes, but it is built into a chip, so you can not determine it there is earth MF or someone just turned on a kitchen refrigirator
r
I wanted to use it like a sensor for gas and water flow meters
r
There is a field in range of ±200 uT
r
Any sensor suitable for natural magnetic field 40 uT also fits for this application
AF
Sensivity of sensor is NOT documented and NOT guaranteed. Possibly it changes from time to time.
r
It has no meaning because only alternating component of a magnetic field is interesting
r
If the changes are notable - the chip suits
r
But now - a 2 powers of magnitude below the desired level
