After some research found that it uses special keyboard keycode instead of sensors. Dmesg keeps repeating this when folded into tablet mode:

[17536.285076] atkbd serio0: Unknown key pressed (translated set 2, code 0xbe on isa0060/serio0).
[17536.285086] atkbd serio0: Use 'setkeycodes e03e <keycode>' to make it known.
[17536.289293] atkbd serio0: Unknown key released (translated set 2, code 0xbe on isa0060/serio0).
[17536.289302] atkbd serio0: Use 'setkeycodes e03e <keycode>' to make it known.

Also found linux script to monitor it: https://gist.github.com/emiller/6488449

Thanks in advance!

This seems to be how Samsung implemented its tablet mode detection too.

[  172.552723] atkbd serio0: Use 'setkeycodes e02c <keycode>' to make it known.
[  172.675819] atkbd serio0: Unknown key released (translated set 2, code 0xac on isa0060/serio0).
[  172.675831] atkbd serio0: Use 'setkeycodes e02c <keycode>' to make it known.

I also found this project where Arch Linux has packaged for tablet mode detection https://github.com/alesya-h/linux_detect_tablet_mode
