Help using a Neptune FS-100 flow sensor with an Arduino/pi? Answered
I'm trying to detect a flow in a 1" pipe with a flow sensor. The best one i could find was made by this company called Neptune (FS-100)
It looks like a basic hall effects flow meter but i am trying to get it to talk to an arduino and I seem to be failing.
It has a TRRS 3.5mm plug on it. I used a volt meter to determine which color wires inside correspond to the TRRS:
Ring: ?? White ??
can someone help me figure out how to get this thing to talk to my arduino?
thanks so much
