Description :
YF-S201 Water Flow Sensor can be used to measure the flow of liquids in both industrial and domestic applications. This sensor basically consists of a plastic valve body, a rotor and a hall effect sensor. The pinwheel rotor rotates when water / liquid flows through the valve and its speed will be directly proportional to the flow rate. The hall effect sensor will provide an electrical pulse with every revolution of the pinwheel rotor. This water flow sensor module can be easily interfaced with Microcontrollers, Arduino Boards and Raspberry Pi. Connect the PWM output of this module to interrupt pin of microcontroller unit and count the number of pulses / interrupt per unit time. The rate of water flow will be directly proportional to the number of pulses counted.
