It's the handle of a water kettle. Behind the circuit board is nothing. There is also no other circuit board in the kettle. Is the yellow thing the beeper? Thanks for any help 🙏

Do beeper services even exist anymore? I would think they all got displaced by cell phones long ago.

I believe they are used in some emergency situations because they use less bandwidth than cellphones and will work when other services won’t.
