More info

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



  • Lowest rated working voltage: DC4.5 5V-24V
  • Maximum operating current: 15 mA (DC: 5V)
  • Working voltage range: DC 5~18V
  • Load capacity: ≤ 10 mA (DC 5V)
  • Temperature: ≤ 80 ℃
  • Operating humidity range: 35%~90%RH (no frost)
  • Allowed pressure: pressure 1.75Mpa
  • Temperature: -25~+80 °C
  • External threads: 1/2'


Note: The color of the sensor is mostly white.
