The Water flow sensor can be used to measure the flow of liquids, i.e. the consumption of liquids in industrial or domestic usage. For example you can make a robotic cocktail dispensing machine, and can use this sensors to accurately measure components like Soda, Water, etc. Water flow sensor consists of a plastic valve body, a water rotor, and a hall effect sensor. When water flows through the rotor, rotor rolls. Its speed changes with different rate of flow. The hall effect sensor outputs the corresponding pulse Signal.

I believe using this should be simple, you just need to connect to Arduino interrupt pin 2, and can measure the number of PWM pulse/interrupt per unit of time. The water flow would be directly proportional to the number of measured pulses.

Connection details:

  • Red wire is +5V.
  • Black wire is GND.
  • White wire is PWM signal output.
