The 1/2 Inch Water Flow Sensor YF-S201 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. 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.

Water flow sensor is mainly consists of plastic valve body, rotor assembly and Hall Current Sensor. Can be used with Water heaters, water vending machine for flow measurement. Very easy to use, 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.
