Use case for ESP32 integrated hall sensor?

[cyberman54]

ESP32 has integrated hall sensor. Could be used to emulate a "reed switch", triggered by a magnet.
Perhaps for resetting NVRAM to values to factory values.

A use case could be to have a "button" on devices which do not provide a hardware button.
E.g. useful for flipping display pages. Could be done by piece of metal or small magnet wiping over the ESP32 chip.

Function especially convenient for cyborgs like @bleeptrack ;-)

couldn't the hall sensor detect a car which drives by or drives over it?

[cyberman54]

@rdmueller no, the sensitivity is far too less for that.
