    Hi to all.
I am looking for some help and advise, I am thinking of using hall effect sensors instead of the reed switches that are commonly used in fine offset sensors. ie Anemometer, wind direction.

Anemometer : I was thinking of using 2 hall effect sensors 180 degrees
opposite each other, so that i would get 2 pulses, as if still
a reed switch.

Wind direction :I was thinking of using 16 hall effect sensors equally spaced
at 22.5 degrees which would give hopefully 16 pulses.

My query is, do hall effect sensors need to be connected separately which would mean a very complicated pcb or can they be connected in series using a common rail.The way I am thinking is that supply and ground can be in seriies and then the output kept separate but to a common point as per diagram.

ANY help and advise will be appreciated.

regards
tyntop.
