Positive supply wire for the water-flow sensor. Adafruit states the sensor has three wires: red (5-15VDC), black (ground), and yellow (Hall effect pulse output).
Ground/return wire for the water-flow sensor. Adafruit states the three-wire mapping includes black as ground.
Pulse output from the Hall effect sensor. Adafruit states the yellow wire is the Hall effect pulse output and each pulse is approximately 2.25 millilitres.
