According to the measurements I was able to make (with a voltmeter) the supply voltage supplied by the VP2 on the steering potentiometer is not constant: it is only present every 3s approximately. It cannot therefore be used to power the hall effect sensor.
This modification works in any case with a WearderDuino TX card which supplies 5V.
I wonder how they do at Davis with their new anemometers with hall effect sensor which seem to be compatible with the older.
So unfortunately I have to replace a reed switch
because the anemometer that I am repairing is that of my Davis VP2.
