Water Flow Sensor (YF-S401)

The YF-S401 Water Flow Sensor is an electronic sensor designed to measure the flow rate of water. It features a plastic body, a water flow rotor assembly, and a Hall-effect sensor. As water flows through the rotor, it spins and alters its speed according to the flow rate. The Hall-effect sensor detects the rotor's speed and converts this information into a digital signal output.

This sensor is suitable for various applications such as monitoring water levels in tanks, controlling water pump operations, improving irrigation system efficiency, and detecting water leaks.
