YF-B7 Water Flow Sensor

Description:
YF-B7 Water Flow Sensor can be used to measure the flow of liquids in both industrial and domestic applications. It consists of a copper body, a water 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 and outputs the corresponding pulse signal.
The hall effect sensor will provide an electrical pulse with every revolution of the pinwheel rotor. The hall effect sensor is sealed from the water pipe and allows the sensor to stay safe and dry.
This water flow sensor module can be easily interfaced with Microcontrollers, Arduino Boards and Raspberry Pi.
This one is suitable to detect flow in a water dispenser or coffee machine.
