KY-025 Reed Switch Analog Inout

Does anyone have a schematic for this unit?

Also, while there is information as a standard reed switch can someone please explain how the Analog is influenced from the magnetic field. There has to be some interaction on the reed switch which would be open for most of the approach of the magnet

A reed switch is just a switch. ON/OFF, and nothing in between.

No other parts are needed to read a switch (pull up can be done in code). The rest of the parts on that board seem like tits on a bull. Leo..

Yes , odd one that - don’t understand the op amp and twiddle bit , unless it’s not really a reed switch
