Feature Request : Hall sensor for ESP32 about easyespnow HOT 4 OPEN

Maybe this one can be shared with the touch input suggested in the other issue.
It does need similar parameters and it is also an input-only device.

Both (Hall sensor and touch input) do give some "analog" output, which can also be used for some use cases. So maybe you may also add a setting to either output a discrete value (0/1) or a value scaled from 0..N (scaled to a set range, taking threshold and upper/lower limit into account.

When I said hall sensor can shutdown power to ESP32 I was thinking about following circuit :

Thanks.

Interesting idea, but needs several modifications in the main Core.

Experimental Hall sensor plugin added in commit 5bb2747 Although i do not know how do you plan to use it, my ESP32 did not return any usable readings, when i moved it near a magnet...
