Thanks guys.Both sketches work well. My flow was too low to produce continous readings! It would only read the first pulse. I need a low-flow water sensor, something that will produce measurements down to 1 mL per second. The seeedstudio water flow meter is only rated from 1-30 L/min (16.6 -500 mL/sec) Does anyone have any recommendations that won't break the bank?
Perhaps a very small water wheel?
