Water Flow Sensor (1/2″) For Arduino

Water Flow Sensor (1/2″) For Arduino

The Water Flow Sensor(1/2″) for Arduino measures the rate of a liquid flowing through it.
The YF-S201 water flow sensor consists of a plastic valve body, flow rotor and hall effect sensor. It is usually used at the inlet end to detect the amount of flow.
