YF-S201 Flow Sensor

The YF-S201 Water Flow Sensor is a precision instrument used to measure the flow rate of water and other non-corrosive liquids in pipelines. It operates on the Hall effect principle, where a rotor spins inside the valve body proportional to the flow rate, generating a frequency output signal. This sensor is ideal for integration with microcontrollers such as Arduino, ESP32, or Raspberry Pi for projects involving water monitoring, irrigation control, or liquid dispensing systems. Key features include a compact design, wide operating voltage range, and high durability. It is commonly used in home automation, industrial equipment, and DIY electronics projects. Choose this sensor for reliable performance, easy interfacing, and cost-effectiveness in water flow measurement applications.
