Hi I have a wireless sensor connected to a flow switch. Most of the time the water will flowing so the switch will be in the closed position.
This is a battery powered wireless sensor so am trying to use as little power as possible.
As I understand it, current will only flow when the switch is closed, but as my switch will be closed most of the time will a larger resistor reduce the current flow? I was thinking 47K or 100K.
Is either pull up or pull down better than the other?
Or is there a better way of doing this?
