Description
The YF-S201 Water Flow Sensor is a device used to measure the flow rate of water or other compatible liquids. It operates using a rotating turbine or blade mechanism that spins as liquid passes through. A Hall effect sensor detects the rotation and generates a pulse signal proportional to the flow rate . This output can be interfaced with microcontrollers or digital systems for real-time monitoring and control. It is commonly used in applications such as water flow monitoring, irrigation systems, industrial process control, and home water management.
